PAIN THAT COMES ON STANDING
You can sit through a meal. You cannot get through a grocery line.
Standing loads the back of the spine. If ten minutes upright is your limit and sitting is a relief, that pattern points at a short list of structures and away from most of the others.

The mechanics of why standing hurts
Upright posture puts the lumbar spine into extension. Extension closes down the facet joints and narrows both the central canal and the foramina. Every structure at the back of the spine gets loaded, and every space at the back of the spine gets smaller.
Sitting reverses it. Flexion opens the canal and unloads the facets, which is why the relief of sitting down is often immediate and complete. That reversal is diagnostic, and it is the opposite of what a disc-dominant back does.
The two usual answers
FACET-MEDIATED PAIN
Axial pain across the low back, worse standing and walking, easier sitting or leaning on a cart. Getting out of a chair is the worst single movement. Pain refers into the buttock and stops around the knee. Confirmed by diagnostic block, treated durably by radiofrequency neurotomy.
NEUROGENIC CLAUDICATION FROM STENOSIS
Heaviness, burning or weakness in both legs that builds with time upright and with distance walked, and clears within a minute or two of sitting. The tell is that a shopping cart buys you more distance than willpower does. Stenosis.
They overlap and frequently coexist, since the facet hypertrophy that causes one contributes to the other. Which is dominant changes what helps, and that is worth settling rather than guessing.
What to notice before your appointment
- Time or distance? Minutes standing still, or blocks walked. Stenosis is distance-limited; facet pain is time-and-position limited.
- Does leaning forward help within a minute? Strongly suggests canal narrowing.
- Do both legs feel it, or just the back? Bilateral leg symptoms move the odds toward the canal.
- Uphill versus downhill. Easier uphill is a stenosis signature and people rarely mention it unless asked.
The part that is not mechanical
Standing tolerance is also a conditioning and terrain question. Hip extensors and deep abdominal wall share the load that facets otherwise carry, and both atrophy quickly once someone starts avoiding standing. Meanwhile glycated, chronically inflamed connective tissue tolerates sustained compression less well than the same tissue in a metabolically healthy system.
So the standing limit is rarely fixed. It usually moves once the load is redistributed and the terrain is addressed, which is why the plan here includes both rather than an injection alone.
Common questions
Why can I walk further than I can stand still?
Walking cycles the load and briefly unloads each side; standing still holds one position under constant compression. Many facet patients report exactly this, and it is a useful detail.
The mechanism is covered in You measure your life in blocks now, not in minutes..
Does a cane or cart help?
Often substantially, and using one is not a defeat. It buys the flexion that opens the canal. Use it to extend your distance, then work on the conditioning that reduces the need.
The detail is in Not everything that runs down a leg is sciatica..
Is standing all day at work making it worse?
It is loading the structures that hurt. Whether it is causing damage is a different question, and usually the answer is no — but tolerance is real and a job that exceeds it daily will keep the problem active.
