About 5 years ago, I hit my shin very hard on some slippery stairs. It was very hard to walk or put weight on it for about a month and if anything touched my shin (including cloths), it would be extremely painful. After the pain was gone. I had a decent size, visible dent in my shin. It hasn't bothered me in a few year, until I hit it again the other day. Now, it is bruised, very painful (it takes my breath away), but I can walk on it. There does seem to be a bit of swelling. It is possible that I fractured or damaged the shin bone? I thought that it was suppose to be one of the strongest bones in the body. Is there any point to going to the doctor now?
