If the attacks persist I would think it may be pancreatitis attacks, I've had pancreatitis attacks all my life, they removed my gallbladder even thuogh there were no stones, and come to find out I had an abnormalty in my bile duct that I was born with, and I've had endoscopic treatment, but I still have pain everyday, and your symptoms describe exactly what mine are, so get a good GI doctor and get some tests done to take a look at that Pancreas! good luck!
