i was in a barfight this past friday, got hit pretty hard in the head, and wound up having a lump, it hurt but i was never really dizzy or close to vomiting or another signs of a concision. Well i still have a lump and it is sore,if you touch it, but I dont seem to have any other symptoms. I have been taking two tablets of Tylenol a day, is there anything else i should do about it
