Hi my name is Margaret I have constant pain in my lower legs, my right knee often becomes very inflamed and so sore. I have had a keyhole exploration of my right knee to which a small shaving of bone was done. They have ruled out arthritis and have called it chronic pain and simply gave me tramadol and diclofenic but they are of little effect. I do not wish to take stronger pain meds as this could cause future problems I just want somebody to tell me what's happening to my legs. I try to keep active by taking a walk every day for 45 minutes at a time. Can you help?
