I had a bruise and now the discoloration is gone but still hurts and itches, whats wrong with it?

I have something similar and asked my doctor. They told me with how hard it was hit the bruise is so deep it can take a very long time to heal and could have injured a nerve. My injury was before Thanksgiving November 2010, still today I have pain occasionally but does seem to VERY SLOWLY be getting less frequent and less painful. Hang in there. If it gets worse, that is when you should have it checked.
