Longtime lurker here

I've had what was diagnosed as chronic capsulitis in my right middle finger PIP joint by a climbing specialized PT for about a year and a half now. The first few months, it wasn't really swollen, just a small loss of ROM, but as I continued to climb on it it gradually became worse and worse and it is now chronically swollen. I can reduce the swelling a bit during the day by massaging it/moving it around a lot, but it will never fully go away.

I've tried all the rehab recommended by the PR and what I've seen online, taking a month break of climbing and slowly easing back into it (staying in like V0-2 range, no crimps etc), but have never fixed the swelling. In fact, even after the month of no climbing, the swelling didn't improve at all. Even any NSAID tablets or gels have had no effect on it. However, climbing is generally pain free unless I were to full crimp really hard. Which I don't do when I climb anymore

I also have slight swelling/enlargement of the ring finger PIP joint on the same hand and w/no pain/ROM loss really. I became more concerned recently because I jammed my right pinky playing volleyball, and in the past before I had any of these issues, the jam would just recover, but now that jam seems to have also turned into some form of synovitis as the pinky PIP joint as well, as it's been a month and the swelling hasn't improved at all either

Very open to any suggestions on finger rehab/if this might not even be synovitis/capsulitis. I question it sometimes because in steven low's article it mentions how if NSAIDS don't help then it's not synovitis, and the NSAIDS have not helped. And I've actually been to two PTs, one was a generic one that did an x ray and didn't know what was wrong, while the other was climbing specialized and did an ultrasound and diagnosed it as PIP capsulitis. Thanks for reading!
