I fell two weeks ago and hit my bum on a metal bed rail. Brusing was horrible but pain I could handle and I thought the issue was resolving. There was also a large knot on this side of the injury. This morning I set down wrong and have caused more injury -- now it is very painful. Should this be seen by a doctor? It is Saturday and a holiday weekend and I would hate to go to a hospital if wouldn't help. Or is there something else I can do to lessen the pain.
