thanks for the query.
I have gone through your mail and could grasp the summmary of your problems. There seem to be two issues. 1. Pains and aches pertaining to the lower stomach(abdomen) with flatulence
and bowel disturbances and 2. Burping and belching
with gaseous distension of the upeer stomach. These symptoms ssuggest both gastric problems as well as problems with the bowels. Usually a combinaation of these are seen in a condition called irritable bowel syndrome
and a lot of these complainyts are due to irregular eating and sleeping patterns. You may require an ultrasound
of the abdomen along with a upper GI endoscopy
and a colonosccopy before starting anny medication.
