Bought a sit-stand desk specifically because of low back ache from sitting. I stand about four hours a day now, spread across the day. Three weeks in the ache is worse, and it is now a specific band across the low back that shows up after roughly 40 minutes of standing. Hard floor, ordinary trainers. Did I buy a solution to the wrong problem?
You bought a real solution and then implemented it at about three times the dose anyone should start with. Standing is a load too, and four hours a day from a standing baseline of zero is a big jump. That band across the low back after 40 minutes is usually fatigue in the muscles holding you upright, plus the very common habit of pushing the pelvis forward and locking the knees. What worked for me:
40 minute blocks is exactly what I was doing, and locked knees is definitely me.
Locked knees with the pelvis forward is the default everyone drifts into. A soft knee and a foot rail fixes most of it without any conscious effort.
Also check the desk height when standing. People set it once and it is usually too high, which parks your shoulders up and arches the low back to compensate. Elbows at roughly 90 degrees with relaxed shoulders. And the monitor has to go up with it — most people raise the desk and forget the screen, then spend all day looking down.
The monitor did not move when the desk did. Obvious miss in hindsight.
Shoes matter more than the desk. Four hours in flat trainers with worn soles on a hard floor is a completely different experience from doing it in something with real support. I keep a pair under the desk and only wear them for standing blocks.
Three weeks is also short. Some soreness while you adapt to a new load is expected, but there is a difference between adaptation soreness that eases and a consistent ache in the same place getting worse. Yours sounds like the second, so back the dose off rather than pushing through it.
Standing desks are overrated marketing, the answer is just moving more.
Half right — movement is the actual variable. But a sit-stand desk is the easiest way to build movement into a job that keeps you in one spot, so I would not throw it out.

Separate vote for the anti-fatigue mat, because it is the thing people skip on the grounds that it looks like an accessory. On concrete or tile it is the reason your feet and back can tolerate standing at all. Mine was about 35 and the difference showed up the same afternoon.
