My boyfriend (age 69) went into have rotator cuff surgery on the right arm. very successful. before and after, both his hands are swollen, painful, etc. He has had doppler test, (showed nothing), Xray (mild arthritis). doctor wants him to see a rheumatologist now. He is also border line diabetic and urinates frequently during the night. Uses a Cpap also. He has been a multi reed jazz musician for 60 years really putting pressure and work out on his fingers and hands. He has had trouble in the past with trigger finger and three surgeries for this condition. right now, he cannot make a fist open a bottle and it does go into the arm......please advise.
