hi, about a month ago I got hit in the shin with a hockey ball, it bruised the skin, and at first felt like there was a slight dent in my shin, but after a week it turned into a hard like lump. the lump is still there no, as well as the bruising, and it can be tender at times, and hurt slightly when a certain amount of pressure is applied, I was wondering what damage may have been done? if its just bruising or something more serious?
