Follow-Up:
I developed this condition just in the last few days. A family member also reports that she has suffered from this on and off the last few years. It seems to re-occur the same time every year (in Sept) but she noticed she did not get it last year. Last year she wasn't around to eat her tomatos when they ripened because she was out of town that month! I started drinking tomato juice a few weeks ago in place of orange juice in the morning due to the low carb diet I am on. Perhaps this is related to a Ph imbalance and the tomatos are the culprit! I will quit the tomato juice immediately and try the baking soda cure someone suggested. Also, I've been told to avoid alcohol, salt, vinegar, etc., anything that will aggravate the burning.
