I had this. Sometimes getting so sore that it was taking my breath away. after
I while I went to GP describ
ed my symptoms and he took a blood test which revealed helicobator pylori (think that's how it's spelt) it is the bacteria around the stomach
which causes an ulcer and acid. A weeks course of 3 separate antibiotics cleared it up. Although I would still have to take Losac to stop an acid. I have noticed foods like onions and spicy foods trigger this off.
