I've had this pain in my ear/jaw for years, since childhood. Every time I go to the doctor, I'm prescribed antibiotics for a ear infection after they look in my ear, but I seen this red and white ulcer like thing in the back of my mouth, that sinks in in the center, and I pushed on it and felt the pain it in my neck/jaw/ear relieve some. Should I be worried? If it was cancer, wouldn't I have died as a child?
