Glucosomine takes about two months to even START to work. Some time back I had a painful knee. My neighbor talked me into using his magnet bandage, and I did. Never expected it to work, but, it did. Pain was gone in 2 days. I was wearing it on the outside, walked into a store, and a woman I dont know said "Oh what did you do to your knee?" I said "My wife and I were doing it dog style, and she ran up under the porch." I thought she would be offended but she wet herself.
