A few times over the last couple of weeks I've woken myself up by biting my lower lip while I'm asleep. This has never happened before in my life. It's always in the same place and seems to be my left canines that suddenly bite down and I wake up. Understandably this is unpleasant and I'm a bit baffled by it. I know I have TMJ so I'm wondering if it's related to that. I've also developed a tingling sensation on the left side of my head and ear recently which comes and goes. Again wondering if it's related. I should probably just go to the gp but feel a bit daft... Anyone else experienced this?
