Since a year I was having stingy motion and mucus back in my throat or nose. From april around I noticed, upper abdomen pain. However I used to have stomach pain and gastritis earlier and used to take pan 40, and it used relax for that day.On July 25 I got loose motion, checked with gastroenterologist after 15days, dooctor suggested me to have ibset, somapraz it and refagut. After the course for 3 weeks I got stingy motion again and sometimes I urge to go bathroom like earlier. Then doctor asked me to continue somapraz 40 and ibset still, im having upper abdomen pain and bloating and urge to go bathroom. Im having some mucus as well dont know whetehr it is due to acid refux or allergic, because I dont feel the acid till my mouth but the mucus if it comes to my mouth it stinks pathetic.My motion sometimes it is dar stool sometimes normal.but as now im having ibset again, my motion is tight but urge to go bathroom thrice somedays.And upper abdomen pain continues.Please help
