The left side of my face felt wierd(stiff, tingling) one evening and when i woke up the next morning the whole left side was tingling and gradually became numb during the day., the numbness moved from my jaw to my lower lip and back again, this have never happened before and i have no idea what to do? I banged my head very hard about a week and a half prior to this - could it have something to do with this? Can wisdom teeth cause this problem as that is what i was told by one person but i have not been having any problems in the dental area so not sure if this would explain it.
