I have been having abdominal pain, some acid reflux , belching , constipation, but I did go once but very small amount, and its hard even to pass gas. The pain is mostly in the upper quadrants and it hurts to urinate but not like a bladder infection and it hurts through to my lower back. I have taken stuff for gas and even pericolace. Not sure if I should just go to ER or try some other otc meds
