<s>[INST] I have been diagnosed with H Pylori 5 weeks ago (gscope - biopsy).The doctor treated me wit antibiotics, Klacid, Flagyl, Nexium and Zantac.The Flagyl made me feel sick and my stomach worse but I finished the course.  I was on a 5 day course.  I feel worse I am so bloated it is not even funny, I get Nauseous in the morning and when I eat I feel better, but then my stomach start feeling bloated again I feel very Uncomfortable and in pain and some kind of movement just below my left side rib, I am scared to eat because its going to make me feel better for a while and then worse again.  My bowel movements seems to be normal but I burp alot.  I am scared of stomach cancer, are these symptoms related to stomach cancer. Sometimes I feel some Uncomfortable on the right side as well. I am only 31 and otherwise in good health.  Please help? [/INST] HI, thanks for using Chat Doctor Stomach cancer would have been seen on endoscopy and would have shown up in the biopsy that you had a few weeks ago. It would not develop in the weeks since the biopsy, cancer takes months to years to develop. Since the biopsy 5 weeks ago did not show cancer, then this is highly, highly unlikely. Bloating is a common symptom and can be related to your history of h pylori, reflux. It can also be due to the use of gas producing foods such as certain vegetables or fruits. Constipation is also a possible cause. The use of reflux medication such as medium, Prilosec, prevail, cipher, may help. I hope this helps </s>
