Dear Snoopy and Dr. Leelah--Thanks for your posts. I read both of Snoopy's remedy suggestions in Clarke and realized that both could be it but that I didn't, as Dr. Leelah said, have enough particulars. I asked my friend, not her husband, but her observations are probably right on the money. They've been married forever.
The pain starts gradually with a tic in the mandible, gradually increasing over a couple of weeks and moving to the cheek. The pain is described as "feeling as if it will explode." Ice applied to the cheek relieves the pain slightly. The pain is worse in the morning, worst upon arising. Sitting still is a necessity because moving makes the pain worse. The pain is now full-blown and unrelenting. Appetite is good but he can't chew. All other bodily functions are normal, no changes, no other discomfort.
