HELLO I had my gastric bypass done on Feb 22,2010 and have lost 39 pounds so far. I am having a hard time with my weight loss because i have alot of pain in my right leg and knee and the doctor says that weight loss and exercise would help but how am I suppose to exercise when I am in pain. I am getting better slowly but surely and I want to reach my goal of 155 pounds. Its always nice to talk with others that have had the surgery to find out how they are dealing with these types of problems.
