Hi I recently dove into a 4 by 4 piece of wood that was cemented into the ground (on accident) I hit my thigh and imediately my leg started to swell, bruise , and tighten up. That whole day my leg was terribly tight. The next day my leg was not tight anymore but still had swelling pain and bruising. Its been a week now and when standing up, or sitting down, or making any sudden movement, I get this rush of pain. Its not a sharp pain but I have never felt someting like it before. It almost feel like its tightening up, and then just goes away
