I woke up with a large lump on the back of my head, sore on the right side, down to my right occipital lobe down to the base of my skull, my neck. My jaw is sore on the right also. I have not bumped my head, so I am a bit alarmed. I have been nauseous and have had blurry vision/double vision lately. What do you think? It is so tender to touch I can't brush my hair. I am a 52 year old woman.
