I had a friend who long ago got a peptic ulcer from xpili bacteria and he said he was near death.I thought I had a wheat allergy and my dr simply nodded his head that it was possible.I was able to eat fried rice until I had difficulty digesting the fried rice.I thought of my buddy and his peptic ulcer and found flagyl is the go to antibiotic.I got the nurse practitioner to prescribe flagyl and it has helped. I may consult a hematologist? I am also going to continue taking flagyl until I run out of pills.
