Hi I'm not sure where to post this because I don't know whats wrong with me. My problem is that my right knee falls from under me when I try to walk (I have to use crutches so I won't fall).It has been like this since christmas and I've been to doctors and they give me all kind of answers like my ligaments are ok, I have oedema in my bones, the cup where the pressure goes on is going (don't know the english word). Nothing can fix this surgically but knee replacement, but I'm too young and I'm little overveight. But for the last year I have lost 10 kilos. I'm in physical therapy, acupuncture, bathe in all kinds of oils to sooth the pain, exercise in water and all things I can think of but nothing works... Oh... and I have had meniscus surgery but that was a small part removed there... I just don't know what to do... I would appreciate any advise...
