i bought a sponsership for a year. i am so happy now i can do more. although yesterday i buggered up my other knee. my left one i screwed up about 10 years ago and yesterday i was trying to get up and i twisted my knee the wrong way and i heard a snapping and really intense pain. i think i have bad knees i already had surgery on my one and i have a feeling i may have to have it on this one. it is always throbbing and i cant walk much on it and its swollen and bruised and this was exactly what happened to my other knee i had surgery on.
