Well, that is unusual. I can see something happening that then causes discomfort at that time but that it triggered an ongoing problem. That's a head scratcher. Clearly you have irritation there. Do you have acid back up, do you think? Does an acid pill like Tagamet help you? I'd try to see if it does. How are other things like weight and your eating habits? Is there times of day when it is worse than others? Any known triggers?
