I think I'm either going mad or have developed some sort of nervous tick... Last night I was sitting down after dinner and felt a kind of pulsing sensation in the tip of my chin - as if a muscle was jerking around. This morning it has stopped - to be replaced by a crawling feeling in my lower lip and around the sides of my mouth. My face feels tight like a drum and the underside of my right jaw is sore as if someone had given me a good punching during the night. Is this TMJ or am I just turning into a nervous wreck. I could SCREEEEAAAMMMM!!
