I found help with an orthopedist who does not do surgery. If your imaging was too soon after the fall, you might want to redo (x-ray would probably suffice) to make sure no fractures. They show up late in imaging. I went through 6 months of pain with MD's not listening and a specialist redid x-rays sure enough, fractures.

I have a PT who doesn't do exercises with me, only massage and ultrasound, and she is gifted. I am lucky because after maybe 6 months of pain like yours, I have been able to walk and walking for some reason helps. I also stay in bed a lot, especially if I make a mistake, because my back is better sitting in bed with lots of pillows behind.

I cannot sit against anything. Which makes me think you might have fractures (I have 7).
