Just an thought also, if it might be postural/repetitive , perhaps an expert chiropractor, they can adjust extremities too, just verify they trained/studied that.
Mine adjusted neck.shoulders, elbow, wrist ,foot, hip - whenever I had a question or new pain come up he checked it out...
I really had the best improvements with my chiro.... but i have chronic repetitive strain/TOS/myofascial pain...
Some are better than others, same as docs and PTs , mechanics,plumbers etc on and on..

always are some very good ones and then not so good ones..
Thumbs - De Quervain's tenosynovitis?? was that checked for? that was one of my first dx when all my RSI/TOS stuff started..

Maybe you should look for a Physiatrist, or rehabilitation physicians, are nerve, muscle, and bone experts who treat injuries or illnesses that affect how you move.
