about a moth ago I spun my foot while dirtbiking (my toes caught a rock, and began to point behind me) and the out side of my knee was swollen, and bruised for almost two weeks. after two weeks i hurt the inside of my knee (just a slight twist, and shock) now my whole knee is swollen and sore. I am able to move and lift with it, but I can only get my heal about 6-8 inches from my butt. Any more than that will not happen. lastly, I also get a little tingle in my knee when it is bent for an extended period of time. THANK YOU VERY MUCH!!!
