question: My daughter came home and said that she stepped on a stick which punctured her foot - no bleeding. I looked and it looks more like she stepped on a straight sharp object. The puncture is a 1/2" long slice going directly into her heel about 1/2-3/4". Today (2 days later) she said it really hurts, but there is no sign of infection, no discoloration, sore to the touch, still no bleeding. She is now suddently getting swelling on her right arm. I'm confused about why the arm. Any suggestions about the painful foot or the swelling arm?
