Hey, there has been a pain in my right leg on the inside part of my knee facing the other leg. The pain started a few months ago. What could I have injured? My next question: Around my knee, at certain times will feel like it s runbling around my knee. When I was looking at it when it went, it looked like my skin was seeping into my leg and going back out and doing this over and over for a short period of time bringing lost of pain. What does this mean?
