Help! I have extreme jaw pain that radiates through the whole right side of my face, especially in my back teeth (upper and lower) and extends behind my ear, to the back of my head. Thinking it was something to do with my teeth, I saw my dentist, who took Xrays and did a series of tests, finding nothing. He insists that it's my sinuses (since it's allergy season), but I've had many sinus infections, and the pain is dull and in a different place. The pain was so bad yesterday, that I had to go to the ER and they gave me Vicodin (yuk!). Please, if anybody has had similar or has any ideas. The pain comes and goes and lasts between 15 minutes to 3-4 hours.
