I get sharp pain in my jaw, near my ear, when I eat for the first time of the day. I think it may have something to do with salivating for the first time of the day too.

Also, and perhaps related is severe ear pain at night,in front of my ear or along the outside of my ear to the degree that it wakes me up and I can't even touch my ear or jaw because it is so sensitive.

Does anyone know what this is?
