My PT has involved some "strengthening" exercises - i'm not sure they're to make me "stronger." B/c I had shoulder surgery in March 2006, I couldn't do anything with my arm until mid-april, and then all this started to hit head on. So, I had lost ALOT of muscle mass/tone in my left arm, and my doctor was worried. That is a good point tho, and i will bring it up when i see him today. Thanks again!
