Hi, A Few Weeks Ago I Experienced Pain In My

Hi, a few weeks ago I experienced pain in my upper/middle back and upper right quadrant. I went to the doctor and he proscribed linzess and an acid reflux medication. The linzess causes severe diarrhea. I'm constantly boated and my stomach rumbles continuously. I'm going to have an ultrasound on my gall bladder/Liver on this coming Tuesday. What do you think?
