Are there any nearby towns or cities where there might be swimming pool resources that you could use? Are you able to drive yet so if there was a pool ssituation you could get yourself there and back? Hang in there and don't do anything that hurts your arm–not a good sign but a signal that you shold try something else for now. Ask your PT for water exercises that are good or you might look online for some reasonable suggestions about water exercises. Or check Amazon–you might find something there in terms of a book that might have good suggestions about water exercises. Don't despair–It really does take a very long time to recover from rotator cuff surgery. When I had mine it really was about a year before I felt fully recovered. Your doctor may be giving you some questionable advice about how much and what kind of exercises you are really ready for. As my doctor said: "If it hurts don't do it!"
