Last friday, I fell through an open heat grate in the floor. My leg had to be pulled up. I have a lot of bruising. Swelling and pain. After a week, the bruising pattern is an oblong pattern starting above my extending about 12 inches in length and five in width. In the center is a hard knot about 2 1/2 inches in diameter. There are sensations of numbness, pain, tingling, cold feelings, and hot feelings shooting up and down the leg
