After two knee replacements a year ago, I was left with great knees , but terrible pain in my lower legs. Nothing helped, and i was faced with the face that i would be in pain the rest of my life. Then i saw this product , and decided to try it, as a last resort. After one day , I can honestly say it worked! The swelling in my legs went down, the burning pain went away and i could walk my dogs without every step being in pain. I was shocked! So i began taking this , and every day i saw a little improvement over the day before. I can now walk 2 miles a day and I am so happy I tried it. It saved my life physically and mentally!
