question: I had/have a very painful bruise with a harder white spot in the center of the bruise on the side of my thigh, about midway up it. I have had it for a week and the surrounding bruised area is going away as bruises normally do. However, the hard circular, almost ball like white center is still there and just as painful as the moment I noticed it. It wasn t from an insect bite and I may have gotten it from playing with my dog too roughly. Is it something I should be worried about?
