On Thursday, I got out of bed and as I started to walk both my ankles and knees started popping. I knew this was not a good sign. Within a few hours my right knee, which had been injured in the past, was starting to swell and pain set in. By Saturday the swelling and pain was so severe that I could not put any weight on it so I was unable to walk. It just so happened that I had called my friend, I knew it was happened to her last year. So she gave me some patches. Within 15 minutes of applying the FASTT Patches to my knee I was able to at least put some weight on it which allowed me to hobble around. By Sunday I was walking with a limp and today, Monday, it is continuing to improve. I am very impressed and that is why I am ordering more of the products. My friend told me go google to find out herbhealthonline to get the patches.
