I m male, 33 yrs old , sometimes in the morning or just after meals or during bumpy bike rides or while bending or leaning for day to day chore I occasionally I feel slight irritation in the lower right side of my abdomen Its like sharp pricking sensations inside linings of my abdomen as if I am being bitten internally...at a times it comes and goes. I used to feel same sort of feeling on left side of my stomach few years ago. Regarding my medical history I have acidic refluxes frequently but they do go away with antacids such as rabeprazole or sonpraz. I have frequent episode of sinusitis , laryngitis and tonsillitis (former two frequently) at the interval of 3-4 months for which I nee to take antibiotics with NSAIDs and antacids. In recent past before 6 months I had mild episode of hepatitis -E which went away within 3 months. I do have gas problem almost everyday.
Discomfort that you mentioned in your right lower abdomen and the way it is troubling you is suggestive of either a chronic appendicitis or a stone in the right lower ureter. To get a clear picture you should get an ultrasound examination of your abdomen done. You also mentioned acid re-flux disease ;you should try to avoid NSAID as they induce gastritis. Continue with omeprazole and try frequent and small meals. Avoid spicy food and beverages. Let me know when ultrasound done. Thanks.
