I fell at work, and had to have xrays taken. Everything was okay, with minor abnormalites to the knee cap. The thing is, I have numbness in a section of my leg, right below the knee, about the size of my palm. If something hits it or if I put pressure on it, it burns intensely. I fell 12 days ago, the swelling is gone and the bruising is fading. My ankle also bruised and swelled, even though I didn't hit it. What else can I do to make the numbness go away?
