That sounds pretty bad. If you cannot see your doctor right away, I have had good results with Zegrid. It is with the other heartburn medications. Just so happens that Walgreens has a coupon for this product at this time too.
I would really advise you to see your primary care physician as soon as possible.

it sounds like it could be an ulcer or maybe even heart problems, you need to see a physician......
