I had an endoscopy done 3 weeks after my GB was removed to allow some renegade stones to pass through. I was nauseated and in pain for weeks afterwards. I also had severe pancreatitus. I am finally starting to feel less nauseated 3 months later, but I am feeling pain in my chest and back again. My Dr. is sending me for more tests to see if my pancreatitus has returned. Just watch your fat intake and eat fresh veggies and fruit for the next couple of weeks. It's boring, but you don't want to suffer, believe me. I had an attack even after I had my GB removed, because of some loose stones floating around in my ducts.
