Flux, when I was at Med school we were taught about referred pain - for instance after abdominal surgery and gas is left in the abdominal cavity it causes referred pain to the tip of the shoulder, or cardiac pain to the jaw is another example. I feel that the pain I get in my jaw/teeth may be similar to the post-surgical pain - especially if the spasm in the gut is near my diaphragm . . I'd be interested in any further comments you may have on this . .Ama
