Since having laser surgery because of a hyperactive gallbladder, I have pain in my right side near the incision, bright yellow urine most of the time, and frequent diarrhea. I try to drink more water, which helps. I ve begun having spasms of pain in my lower abdomen-not frequently-and sometimes feel like I want to vomit, but not overpowering. With that, also a sense of urgency that I need to have a bowel movement.
