Well I can say that when I was given my meds my discomfort got worse but I stuck with it so I could get better. I was also given and antispasmatic to calm my digestive tract. Its was Hysocomine, levbid, donnatal or Bentyl. Those work well for that until your stomach can heal enough.
Have you always stayed on the meds long enough to let them work? Mine took 3 weeks to work. Some side affects go away too. Just need towork through them
Talk to your doctor about the antispasmatics along with a ppi so you can get bettter.
Possibly there is a gallblader issue had any other tests for your pain? Did your GI scope you?
good luck
