All that I can do is to relay my situation. My left shoulder was in pain and I couldn't do much with it. Also, the middle finger in my left-hand was a "trigger finger". I don't know if the two are related. I had physical therapy for my shoulder a couple of years ago and I'm still doing the movements that were recommended. Yesterday morning following my daily exercise schedule, I did three pull-ups (overhand) and no pain. As for the trigger finger, I found a book with hand, finger and wrist exercises, "Fingernastics" by Quercia & Crescione (inexpensive on-line) which has lots of photos to explain the exercises. The trigger finger is fading away slowly and my hands, fingers are in good shape. My observation is that these kinds of physical ailments take time, years, to heal. For what it's worth, I'm still studying and practice my music.
