I am a female age 46. Every day, for about 20 days now, I get up between 3 and 4 AM feeling giddy, uneasy with burning, and pain in the stomach and then pass gas in about 15 to 20 minutes which makes it little better and within another 15 to 30 minutes go to the potty which makes it much better and then stomachache subsides slowly in half an hour or so. Why is this happening? Any test to be done? Stomach pain is not severe. It is bearable. Thanks.
