I have severe pain from the base of my skull, on its right side, extending up to the middle of my skull, still in the back of the skull; and there is also swelling in this area. Along with this, i have excessive burping, but do not have any abdominal pain. I have had this condition for almost 48 hours. The excessive burping has diminished; however, the pain and swelling in the back of my skull has not diminished.
