hi I've been suffering with belching for about six months now ,others symptoms include sore ribs ,back ,muscles and aching jaw ,insomnia ,been prescribed omeprazole 20mg ,which doesn't seem to help much .Had a camera down into my stomach and there was a slight sign of gastritis ,also been for scan to check for gallstones ,nothing picked up ! GP has said it could be stress related ,symptoms come and go ,varying in severity from some days feeling fine to other days being rotten others .wondering if you could help
