Hi, I experienced an awkward cramp behind my right ear leading to my neck, a few days ago. Since then, my inner right ear and bottom of my skull has been hurting. Excedrin has not worked. Yesterday, I hit the top of my right cheek bone on the frame of my car door, while leaning over to put my laptop on the seat. I experienced a terrible pain across the whole back of my skull. Today. only my right inner ear leading to my right bottom side of my skull still hurts. Does this sound like a pulled muscle or a need to visit the emergency room
