question: about two months ago I noticed a hard lump the size of a half dollar on my right shin, it was tender and did hurt a little when touched or rub against something...now it is now a knot the size of a chick pea. My whole leg hurts from that spot down..not to bad but it still hurts..also my foot really hurts almost as if something fell on it..it mainly hurts when I stand and walk but its always hurting. I can't remember any injury to make the lump appear and I haven't suffered any injury to make my leg and foot hurt...Please help, I am getting worried.
