Your symptoms sound like pancreatitis (chronic) or bile duct problems. I have pancreatitis and my pain was upper rt. quadrant. Don't have many other signs, but one of my pancreatic enzymes were elevated. I had a CT of abdomen, and MRI of pancreas. Both showed acute pancreatitis. I was not getting better, so they did an EUS which is an endoscopy hooked up to an US machine. He saw the head of pancreas was enlarged..took a biopsy and it came back as no cancer. This test also shows liver, abdomen, duodenum, bile ducts and especially looks for cancer. I would ask your doctor if he can do one of them. Good luck~
