Hey claudia, I had that experience to a minor degree towards the end of my wait.
My hips were too far gone for every ache and pain to leave, but I was misdiagnosed and kept taking physical therapy at a stretch of three months each. My hips usually felt better during it, but the pain was still there.
By that point, looking back on it I was bone on bone, so I guess no flap to fall into place or anything to shift. My last hurrah in this regard was when I threw up my hands and took an intensive fitness boot camp for twelve weeks to push through and get rid of this problem.
Three times per week I took a two hour class with a trainer who drove us mercilessly. I had told her about my muscular pain and tightness, and (as I believed) answered 'no' when she asked if it was arthritis. So we did weights, all sorts of exercises with very little respite, sprinting on the treadmill and my personal torture device, the stair machine. All painful, but I thought less so than before.
Towards the end of the whole thing, I did notice less 'muscular' pain and more ROM. That held up for about three months while playing soccer, until the dislocations of one hip started. After that and the diagnosis of OA, there was no alternative, as all surgeons looked at both hips and said they had to be done now.
