... don't need surgery right now because it is mild but I am in a lot of pain, my knees lock, pop, give out on me, get stuck and wake me up in the morning throbbing with pain. I can barely go up and downstairs. I can't even walk that far without pain and have to sit down. I use to walk bridges and walk around the block and now I can't do that. I also need to lose weight. How can I lose if I can't walk. I can't take a lot of medication because I had gastric bypass and can't take medication with aspirin in them. So I am limited. I need something for pain. Please help!
