Dear Patient the symtoms you are describing are unspecific and can have several reasons, i will try to give you a helpful overview. You haven t said how long this is going on, so i will make a few suggestions what it could be depending on the time scale: 1. If this is going on just for a few days it could simply be a stomach bug/ stomach infection= gastroenteritis caused by bacteria or virus and would mostly go away by itself within a week approximately 2. If this is going on for a longer period, it could be a stomach acid problem like gastritis or ulcer. This can be ruled out by a gastroscopy. Also a stomach bacteria infection with so called helicobacter should be ruled out by a stool sample. This can be treated with acid blocker pills like pantoprazole. 3. it could be other infections in the abdomen, so i recommend an ultrasound of gall bladder, liver, pancreas and kidneys if the problem persists to rule that out, also a general blood test for infection parameters like so called crp, bsg and white blood cells is advisable. Your gp in town will narrow down the reasons by a physical examination and see which cause is most likely and do any of the diagnostics suggested above to find out whats exactly wrong. Hope this is helping you , if you have any clarificatons you can get back to me, if this was helpful please kindly rate my answer. Best regards
