I am experiencing some serious lower back and hip pain lately. I think it is syatic nerve issues. But now my knee is hurting and my upper thigh feels like it is on fire. The area right around my knee also feel like it is on fire, albeit, not an extremely hot fire....I just don't know what to do. I have went to the doctor, the chiropractor, and am now taking an anti-inflamatory medicine and a mucle relaxer but it is not helping the pain in my thigh and knee. Has anyone ever experienced these symptoms? Do you have any idea what I might have done to myself?!?!
