I have a lump on my right leg, its location is on the out thigh near the knee. I ve had it since I was 13... I am now 26. When I would walk the lump would get a little sore after I was walking, it was barely noticeable. I was helping someone move recently and today when I was walking off a curb I felt like I put to much pressure on it and the area on the lump had a sharp pain, when I continued to walk I can feel the area of the lump rubbing op against something but not sure what. It wasn t to soar but I can feel the outer part of the knee is if it was going to buckle, I m now icing it with my leg straight, and the soreness has gone down, though I can still feel some scrape on my knee. Has anyone have an idea of what the lump is, and how I may have just now hurt my knee?
