I bruised my shin last week and it came up in a lump... it's been constantly hurting. Now the bruise seems to have gone but it come up as a giant red mark? It looks like a burn but feels like servire sunburn and hurts when I walk and make contact?
It sounds like extra fluid build up from the swelling and it may need to be drained by your doctor. If it is causing you a lot of problems, go to your doctor.
