Hi Dr Siegel, I hit my shins about a month ago really hard on a metal bench. It was extremely painful and I had difficulty walking for the rest of the day. It has been tender to touch ever since and a dark line bruise appeared right away and has not gone away since. My shins also feel very different, there are huge lumps. I was wondering if this is something I should have my doctor check out? I am very much into fitness and go running and I don t want to make it worse.
