I am a 64 very active woman, used to playing tennis, taking spin classes and jogging, doing something daily. Had torn meniscus in right knee in 2006 when they cleaned out some arthritis. Now I have pain again, can walk fine but hurts to go down hill, run or bend my knee like in tennis, gardening, etc. XRay showed arthritis in right knee, slight in left. bone alignment was fine. I have stopped all aerobics but walking and doing exercises to strengthen the knee, but they hurt alittle afterward doing the exercises. I heard about boswellia and curcumin as a natural way to relieve the pain and help the joint. I can t live on advil the rest of my life. Do you recommend such a supplement? Been taking glucosamine, etc. calcium for years. Thanks Liz
