I have had surgery on both my knees. My left knee was done in 2001, and the other was done in 2005. On my left knee the doctor told me that I had a torn meniscus. On my right knee they couldn't see what was going on, so they told me the only solution would be to go through surgery. Well it had only been 6 months when my right knee started swelling again. I went back they took out the fluid and injected my knee with cortisone. Then 1 month later again, then my left knee swelled up a week after that. What's up with that! No doctor can tell me what I have or why it's happening. I've been tested for gout, arthritis, and my results come out negative. I don't know what to do anymore. I take Ibuprofen, and I started taking Glucocerin, it's to rebuild cartilage. Well anyway, can someone please advise if something else has worked for you?
