It all started about January when I kept having burning pain and the top left side of abdomen I ignored it coz it went away and came back now and then until last month when it was horrid at first doctor said it was heartburn and prescribed PPI after  giving me all 3 types and me explaining it's not working i went to a&e they prescribed omoperazole 40mg one a day and said it's suspected Hpylori infection when I went back to GP they then said they couldn't test for hplyori now coz I took the omerprazole and prescribed me two different kinds of antibiotics which done nothing but take the gurgling sound away but burning and stinging was still there so to cut a long story short I have now been referred to cancer clinic for emergency endoscopy and I'm worried and just want to know what's going on as docotor said it could be stomach ulcer
