Any burning pain? What kind of pain?
My husband suffered nerve damage from a "capsular tightening" operation in his shoulder (not the same operation as yours-but they do operate at the same spot). Nerve pain is burning pain - and he is actually disabled from the pain, can't work, can't play, can't boat. The surgery was in May 1999.
I hear it can take up to 6 months to recover from rotator cuff surgery. Hopefully you don't have burning pain. If its other than burning pain, I would consider that a good thing!
