Over two weeks ago, I injured my shin falling UP the stairs. A large goose egg popped up and my shin, ankle and foot swelled. I iced it and elevated it for two days. The swelling and goose egg stayed for a week. After a week, the generalized swelling went down, but the goose egg remained and developed a red itchy rash on top of it. Now two and a half weeks later, and the goose egg and really itchy red rash remain. Any ideas why the rash??
