I hit my leg really hard trying to jump onto the loading dock at my work. It hit a large piece of diamond plate steel. It was very painful, but I forced myself to walk and get back to work. It has been more than a week now. It never bruised and it doesn t hurt unless I stretch the skin. I can hit it as hard as i want and it feels normal; maybe a little tender in some parts, but not nearly as painful as stretching the skin. It s on the middle of my shin. what could this possibly be? I m a little confused and worried at the same time.
