FIRST PRESCRIPTION

Most people have never heard this part: when a back flare or a fresh back injury gets a first opioid prescription, the odds of still being on opioids months later rise with every extra day in that first supply. For most flares, ibuprofen with acetaminophen, TENS, vibration and steady movement come first. Some backs need more for a short time.

I am writing this on a broken left leg, so let me explain why a back pain site is hearing from me about it.

Why is a doctor with a broken ankle writing about back pain?

On October 11, 2026, a little before 6 a.m., I stopped on the highway to get a woman out of a burning car. While I was moving her to the shoulder, a hit-and-run driver struck me. She did well. I ended up with a medial malleolus fracture and a fibula fracture in my left leg, an ankle cut of about 15 centimeters that tore the tibial artery, roughly 40% of my blood volume gone, a trauma team activation and two broken ribs. No surgery was needed, and the wound was closed.

I have kept working, though I cannot stand long enough yet to do my full load of procedures. Update, October 26: I hit that target. Full function is back, and so is my full procedure load.

In the ER I was offered opioids again and again, and I declined every time. The reason I declined is the same reason this matters for your back.

How does one opioid prescription for back pain turn into years?

Almost nobody with a bad back sets out to take opioids long term. It starts on a Tuesday when you bend for a laundry basket and cannot straighten up. You get a prescription that seems perfectly sensible. Then the flare lasts longer than the bottle, and there is a refill.

That sequence is exactly what the data flags. In commercially insured adults with no cancer and no recent opioid use, the CDC found that the probability of long-term use rose with each day of opioids supplied in the first episode. The steepest increases followed day five and day thirty-one, once a second prescription or refill was added, when the cumulative dose reached 700 morphine milligram equivalents, and when the first prescription was written for 10 or 30 days.¹

So the size of the first script is not a detail. It is the lever. A three-day supply and a thirty-day supply for the same flare are not the same decision.

Are some back pain patients at higher risk from a first prescription?

Yes, and the risk sits more in the person than in the injury. A large study of surgical patients who had not been using opioids found that 5.9% to 6.5% were still filling opioid prescriptions three to six months after minor or major operations, compared with 0.4% of people who had no surgery. How big the operation was did not predict who kept using. Tobacco use, alcohol and drug use disorders, mood and anxiety disorders, and pain conditions that were there before surgery did.²

That study was about surgery, not back flares, but look at the last item on the list. Back pain before the operation raised the adjusted odds of persistent use to 1.57, the highest of the pain conditions the authors named.² Someone with a long-standing back problem already carries that predictor before the first pill. Add poor sleep, a stressful stretch or a history of depression and the terrain gets steeper. That is why I would rather your first move for a flare be something other than an opioid.

It was also why I said no. Minimizing that first exposure is worth the effort. I did not want to set myself up for a medicine I might not need down the road.

What should you try first for a back pain flare?

For the first couple of days after my injury, I relied on ibuprofen and acetaminophen and on a short list of devices: TENS, electrical muscle stimulation (EMS), localized vibration from a plate, and infrared light. I think of the devices as distractive tools. They hand the spinal cord competing signals so the pain signal gets less of a hearing. There is nothing woo-woo in it. Each one has a mechanism.

• Ibuprofen plus acetaminophen, on a schedule. In a randomized emergency department trial of 411 adults with acute arm or leg pain, a single dose of ibuprofen 400 mg with acetaminophen 1,000 mg matched three opioid combinations at two hours closely enough that the gap was neither statistically significant nor clinically important.³ It was one dose for limb pain, not back pain, and side effects were not studied. Check with your doctor if you have kidney disease, ulcers or take a blood thinner.
• TENS. Thin, slow fibers carry pain; thick, fast fibers carry touch and pressure. At the spinal cord they compete, which is the gate control theory of pain.⁴ TENS feeds the fast fibers. Across 381 randomized trials and 24,532 participants, pain scores were lower than with placebo during or immediately after TENS. Reviewers rated that evidence moderate in certainty, saw nothing serious go wrong, and found acute pain responded as well as chronic.⁵ See TENS for back pain and the home TENS unit for nights and workdays.
• Vibration. Same thick fibers, same gate. Our vibration platform also wakes up the muscles that hold the spine steady.
• Light. Red and near-infrared light acts on cytochrome c oxidase in the mitochondria, raising ATP and lowering inflammatory markers in activated cells. Most of that work is in cells and animals, including traumatic injury models.⁶ It is promising, not settled. Ours is laser therapy for back pain.
• Movement. Bed rest makes a flare last longer. Short, frequent walks and position changes beat lying still. Our guide to the first 48 hours of a flare lays out the order, and what not to do with a back that has just gone covers the traps.

These tools are part of our physician-directed physiotherapy for back pain.

Why did my pain stay low enough to skip the opioid?

Partly luck of chemistry. After major trauma the brain turns on a descending pain-suppression pathway driven by endorphins, adrenaline and other chemical messengers. This stress-induced analgesia varies enormously from one person to another.⁷ In my case both endorphins and epinephrine were surging, which is why the pain stayed muted. A back flare at 2 a.m. does not come with that adrenaline surge, which is one more reason not to copy my exact plan.

Does this mean you should refuse an opioid for back pain?

No. This was my own path, and it may not be yours. Some patients need opioids, sometimes for a fracture, sometimes for a nerve that is badly compressed. Pain that is left raw keeps you from walking and sleeping, and a back that cannot move does not recover. Every individual is different, and the right plan starts with the patient who actually walks in, not with an assumption about them.

What I am asking is that declining, or keeping the course as short as possible, gets discussed. Sometimes it works. It is almost never offered.

What if you are already taking opioids for your back?

Then stewardship means something different for you. It is harm reduction for an individual, not a blanket rule in either direction. We help patients who want to come down taper by treating the source of the pain with interventional procedures, such as lumbar radiofrequency ablation for facet pain, while keeping them out of withdrawal. Nobody gets cut off.

Frequently asked questions

How many days of opioids are too many for a back flare?

There is no safe cutoff, but the CDC analysis found the steepest rises in long-term use after day 5 and day 31 of the first episode. If an opioid is needed, the shortest course that gets you moving is the goal.

Can TENS help a back pain flare at home?

Yes, for many people. A review of 381 trials found pain was lower during and right after TENS than with placebo. A home unit lets you use it at night or after work, once a physician has set it up for you.

Is ibuprofen with acetaminophen as strong as an opioid?

For acute limb pain in one emergency department trial, a single dose relieved pain about as well as three opioid combinations at two hours. That trial did not study back pain or repeated doses, so ask your doctor how it fits your situation.

LOW-CARB DIET FOR BACK PAIN

A low-carb diet for back pain works on what sits behind the spine: high insulin, belly fat and the inflammation they feed. It is not a cure for a disc. Done well, it lowers the chemical load on every joint you have. Plan the first week, because that is when people quit.

Here is the trap. In the first few days, a low-carb plan can make a sore back feel worse. You get cramps. You feel light-headed when you stand up. You think it is a flare, so you stop. The plan did not fail. It was working, and nobody told you what working feels like.

We now have a clear map for that week. On October 2, 2026, the Society of Metabolic Health Practitioners published a guideline on how doctors should start and run low-carb care. We use it here as the supporting document. Dr. Padda holds this society’s Metabolic Health Practitioner credential. He did not write or vote on this guideline.

Can a low-carb diet help back pain?

It can, through the terrain the spine lives in. The 2026 guideline says cutting carbs lowers high insulin, shrinks the fat packed around the organs and calms inflammation. Each of those reaches your back.

High insulin and high blood sugar stiffen the collagen in discs and joints. Belly fat is not just padding. It sends out inflammatory signals all day, and those signals lower the point where pressure turns into pain. That is why two people with the same disc bulge can feel so different. We explain that chain in more detail on our page about metabolic health and back pain.

The guideline does not name back pain as a target. It does say something useful. As metabolic health improves, joint pain may improve too, so the medicines for it need review. Our position goes further. In Dr. Padda’s practice, roughly 93% of chronic pain involves metabolic dysfunction. Practice-reported figures from our own population, not trial outcomes, and individual results vary.

Will losing weight help my lower back pain?

Yes, but the scale is the slowest number to move and the least important one. Less weight means less load on the lower spine. The bigger win is chemical. Insulin and inflammation can start to fall before the scale moves at all. We cover the load side on our page about weight and the lumbar spine.

Dr. Padda learned this the hard way. For years he was a strict vegetarian who defended the standard diet advice. A plate of beef at a Kansas City barbecue joint ended that. The physiology changed his mind, and he now tells patients so. Red meat and fish are on our plate. Industrial seed oils and refined grains are off it. Real olive oil is fine.

What do you eat on a low-carb plan?

The guideline keeps it simple. Low-carb means under 130 grams of carbohydrate a day. Most people reach ketosis, the fat-burning state, somewhere under 50 grams. You do not have to be in ketosis to get a metabolic benefit.

• Protein first. About 25 to 30 grams a meal. Muscle guards the spine, and it also burns blood sugar.
• Whole foods. Meat, fish, eggs, dairy and vegetables that grow above the ground.
• Carbs from plants, not packages. Leafy greens, tomatoes, olives, avocados and berries. Bread, pasta, rice, cereal and potatoes go.
• Fat until you are full. The guideline says counting calories is not generally needed. Count total carbs, not “net” carbs.

Cost is the first objection, and it is fair. The guideline says this way of eating costs about the same as a standard diet. It has been used in low-income communities. The harder part is not the grocery bill. It is a shift schedule and a break room built around chips and soda. That is a system problem, not a willpower problem, and we plan around it with you.

Is back pain a common symptom of the keto diet?

Muscle cramps are, and a cramp in the low back feels a lot like a flare. The guideline explains why. When carbs drop, insulin falls. Then the kidneys let go of salt and water. Start-up symptoms begin within two to three days. They often pass in a few days, but can last two to four weeks.

Watch for cramps, headache, tiredness, light-headedness and constipation. A cramp that comes and goes is different from the guarding spasm of an injured back. Treat the salt loss first.

• Salt. The guideline suggests 2 to 3 grams of sodium a day for most people. That is 5 to 7 grams of salt. Salt your food or drink bone broth.
• Potassium. Leafy greens, tomatoes, cucumbers, zucchini and eggplant.
• Magnesium for cramps. 200 to 400 mg a day, if you have no kidney disease, are not pregnant and have no nerve-muscle disease. A spoonful of pickle juice or yellow mustard also works for some.
• Water. At least 2 liters a day if you get constipated.

If you have heart or kidney disease, your salt and protein targets are your doctor’s call, not this list’s.

Why do I feel dizzy when I stand up on low-carb?

This is the part a back patient most needs to hear. The same salt and water loss lowers blood pressure. If you already take a blood pressure pill, the pill and the diet now push the same way. You stand up from a chair your back already hates, the room tilts, and you grab the counter. A fall is the last thing a sore spine needs.

The guideline says to check your blood pressure at home every day at the start. Blood pressure medicines get reviewed when you begin, then every two to four weeks. Medication changes are made by your doctor, especially insulin, sulfonylureas, SGLT2 inhibitors and blood pressure drugs. Never change a dose on your own. Bring your readings. They tell us when it is time.

Your pain pills belong on that list too. The guideline names NSAIDs, such as ibuprofen and naproxen, and opioid pain medicines among the drugs that can push sodium too low. Low sodium adds to the dizziness and cramps of the first week. Show your doctor every pain pill you take, including the ones you buy at the store.

What blood tests should I get first?

The guideline’s starting tests include weight, waist, blood pressure, a metabolic panel, cholesterol and A1C. It lists fasting insulin as an optional extra. We do not treat it as optional. In our clinic, a fasting insulin above 10 µIU/mL is high risk. We also check GGT, a liver enzyme, and flag it above 20 U/L. Insulin climbs years before blood sugar does. A normal A1C can hide a back that is living in an inflamed body.

One honest limit. This guideline is an expert consensus, not a clinical trial. All 18 of its statements cleared a 70% agreement bar. The review behind it did not grade the evidence, and some authors have paid ties to the society.

So what do you do Monday?

Get the pain generator examined. An injection or a block can buy you the window to walk again. Then change what is on the plate. Salt your food the first week. Take your blood pressure every morning. Walk after dinner, because working muscle pulls sugar out of the blood. Protect your sleep, since short nights raise insulin resistance and lower your pain threshold.

Treat this like an injection. It needs a plan, a start date and follow-up. Your spine is carrying more than your weight. It is carrying your blood work. You can change that load, starting this week.

Our diet and metabolic health coaching page lays out the step-by-step eating protocol we use with back patients, from walking after meals to the eating window.

Frequently asked questions

Is ketosis hard on your kidneys?

For most people, no, but kidney disease changes the plan. The 2026 guideline sets protein near 0.8 grams per kilogram of body weight a day for people with kidney disease. Ketosis from food is also not the same as diabetic ketoacidosis. Diet-driven ketone levels stay far below that dangerous range.

Do I need to stay in ketosis for my back?

No. The guideline describes low-carb as a range. Under 130 grams a day already counts, and ketosis is not always needed for metabolic benefit. We start where you can stay, then adjust from your labs and your pain diary.

Will my cholesterol go up on a low-carb diet?

LDL can rise for a while during weight loss and often returns to where it started. HDL usually rises and triglycerides fall. The guideline’s authors say some questions remain until long-term heart studies are done, so we recheck your numbers rather than guess.

FLARES

Back pain flares when a sensitized segment sitting near its threshold gets pushed over by load, short sleep or stress. In the first 48 hours, keep moving, shorten the sitting, take the analgesic you know works on a schedule, and protect two nights of sleep. A flare is not a relapse and it is not evidence the plan failed.

A flare is the most predictable feature of an established back problem, and having a rehearsed response to it changes how long it lasts.

What causes back pain to flare up?

A sensitized segment sitting close to its threshold, plus something that pushed it over. The structure has not deteriorated overnight. What has changed is the margin — and the margin is narrowed by things that have nothing to do with your back.

Three drivers account for most flares we see. Load is the obvious one: a longer drive, a weekend of unusual work, a flight. Sleep is the one people discount, and it is at least as powerful — two short nights measurably lower pain thresholds, so the same load produces more pain for no change in tissue. Sleep is an input here, not just a casualty.

The third is not biological. Flares cluster around deadlines, bereavements, money and a move to a new home. That is not a claim that the pain is psychological — it is a claim about threshold. A nervous system running hot reports the same signal louder, and pretending otherwise leaves the most modifiable driver off the plan.

What should I do in the first 48 hours of a flare-up?

• Do not stop moving, and do not test it either. The instinct to check whether it still hurts by reproducing the movement keeps the segment provoked. Move often, avoid the one position that reliably spikes it.
• Shorten the sitting, not the walking. Most flares are worse in sustained flexion and better upright. If the drive is worse than the walk, that is your instruction for the week.
• Take the analgesic you already know works, on a schedule, for a few days. Intermittent dosing at peak pain is how people conclude nothing helps.
• Protect two nights of sleep deliberately. Of everything on this list, this is the one with the largest effect and the least attention.
• Do not re-scan. A flare in a known pattern does not need imaging, and imaging it will find the same degenerative changes it found last time. Those findings did not change.

When is a flare-up a sign of something more serious?

The pattern is what makes it a flare: it feels like your pain, in your distribution, provoked by the things that usually provoke it. Three departures from that pattern are worth acting on rather than waiting out.

• New weakness. Not painful-and-guarded — a foot that catches on a stair, a leg that gives way. A toe catching on stairs is weakness, and it runs on a different clock than pain does.
• A different distribution. Pain that has moved into a new leg, or crossed to the other side, is a new question rather than a worse version of the old one.
• Anything on the short list. Bladder or bowel change, saddle numbness, fever, unexplained weight loss. Almost everything on this site can wait two weeks; that page cannot.

What can flare-ups tell your doctor?

They are diagnostic. What provokes a flare and what settles it narrows the structure more reliably than a description of the pain at rest, because it is a repeated natural experiment you have already run several times. Extension and rotation provoking it points one way; sustained flexion points another; rolling over in bed points at the sacroiliac joint.

Which is why the most useful thing you can bring to an appointment is not the worst day. It is the pattern across the last three flares — what set them off, what shortened them, and whether they are getting closer together. Diminishing returns are information, and so is a shortening interval.

Between visits, a home TENS unit is one option a physician may order for flares that come on at night or after work.

Frequently asked questions

What does a back pain flare-up feel like?

It feels like your usual pain, only louder: the same place, the same spread and set off by the things that usually set it off. The structure has not worn out overnight. What changed is the margin between your everyday load and your pain threshold. Pain in a new place, a new leg or with new weakness is not a flare and needs a different response.

What is the worst thing you can do during a back flare-up?

Stop moving, or keep testing it. Repeating the movement to check whether it still hurts keeps the segment provoked. Taking a painkiller only when the pain peaks is how people conclude nothing works; take the one you know helps on a schedule for a few days. And do not rush to re-scan a flare in a familiar pattern, because it will show the same changes as last time.

Can stress cause a back pain flare-up?

Yes, through your pain threshold rather than your spine. Flares cluster around deadlines, bereavements, money worries and a move to a new home. That does not mean the pain is psychological. A nervous system running hot reports the same signal louder, so stress belongs on the plan next to load and sleep. Two short nights of sleep lower that threshold too.

Does a flare-up mean my back treatment failed?

No. A flare is not a relapse and it is not evidence the plan failed. It is the most predictable feature of an established back problem, and a rehearsed response shortens it. What matters is the pattern across your last three flares: what set them off, what shortened them, and whether they are coming closer together. Bring that pattern to your appointment.

WHAT NOT TO DO

With a back that has just gone, do not go to bed, do not start an opioid, do not get a scan in the first six weeks, and do not buy a lumbar belt. Most acute (new and short-term) back pain settles. Yet three of those four are still being recommended.

Start with the baseline, because it changes how you read everything below. A community inception cohort (a study that follows people from the first days of an episode) found that most improved substantially within six weeks. So the treatments on offer are competing against a condition that largely resolves on its own. That means the ones that slow recovery down do real harm, even when they feel like care.

Should you stay in bed when your back goes out?

Rest is the most natural response and one of the least useful. Guideline reviews agree that advice to stay active outperforms rest for acute low back pain. The gap is not subtle. The mechanism is not mysterious. Trunk muscles lose endurance quickly and the segment stiffens. You get up two days later with less capacity than you went down with.

Relative modification (changing only the activities that load the back) is a different thing, and it is sensible. Skip the deadlifts, keep walking. What you do in the first fourteen days decides more than most of what follows.

Do opioids help acute back pain?

This is the clearest result in the recent research, and it deserves to be stated plainly. The OPAL trial randomized people with acute back and neck pain to an opioid or to placebo, on top of guideline care. At six weeks the opioid group was not better. They did have more adverse events (side effects and harms). At one year they reported slightly worse pain. Earlier dose-ranging work in chronic low back pain had already shown small effects. Those effects were dose-limited by tolerability and clinically marginal.

Our position on opioids is not abstinence and never has been. It is that starting one for an acute back is a bad trade on the evidence. The population that arrives here on high doses usually got there one reasonable-seeming prescription at a time.

Do you need an MRI for acute back pain?

Absent a red flag, early imaging does not improve outcomes. The systematic review comparing imaging against no imaging found no benefit in pain, function or quality of life, and imaging costs more. What it reliably produces is findings. Past forty, nearly every lumbar MRI shows disc desiccation (a drier disc), a bulge, or facet arthrosis. Those same findings are also present in people with no pain at all.

A scan taken too early does not answer the question. It supplies a likely-looking culprit that then shapes every conversation afterward. Your scan described a back that belongs to somebody your age.

The findings that do earn an urgent scan are a short list, and it is short on purpose.

Does a back brace help lower back pain?

Lumbar supports have been studied mostly as workplace prevention, and the evidence does not support them for that. Worn during an episode, they do what a collar does to a neck. They take over the work the muscle needs to be doing. If you already own one, use it for a specific heavy task, not as a garment.

What should you do instead when your back goes out?

Keep moving within tolerance. Use a simple analgesic (pain reliever) if you want one. Sleep as well as the pain allows. Give it six weeks before concluding anything. Exercise is the treatment with the most consistent support — the type matters far less than that it happens. That is the most freeing finding in this field. Physical therapy fails most often when nobody established what it was treating.

And if it has not moved at six weeks, the question changes. It moves from how to manage it to which structure is generating it. That question is answerable. There is no scan that finds facet pain, which is exactly why so many people are still looking.

If your physician does order support, our back brace page explains how it should fit and why it never replaces your exercises.

Frequently asked questions

What is the worst thing you can do for lower back pain?

Going to bed. Rest feels protective. But advice to stay active outperforms rest for acute low back pain, and the gap is not subtle. Trunk muscles lose endurance quickly and the segment stiffens. You get up two days later with less capacity than you went down with. Starting an opioid for a back that has just gone is a close second.

How long does it take for a back that has gone out to get better?

Most people improve substantially within six weeks. In a community cohort that followed people from the first days of an episode, that was the usual course. So give it six weeks before concluding anything. If it has not moved by then, the question changes from how to manage it to which structure is generating it. That question is answerable.

Can I keep exercising with lower back pain?

Yes, with sensible changes. Skip the deadlifts, keep walking. Exercise is the treatment with the most consistent support for back pain, and the type matters far less than that it happens. Changing the specific heavy task is sensible. Stopping everything is not, because the muscles you rest are the ones your back needs working.

What painkiller is best when your back goes out?

A simple analgesic if you want one, not an opioid. The OPAL trial gave people with acute back and neck pain an opioid or placebo. Those on the opioid were not better at six weeks. They had more adverse events and reported slightly worse pain at one year. That makes starting an opioid for an acute back a bad trade on the evidence.
