I believe I have read that pancreatitis is worse when lying down and it helps to sit up and lean forward. I started out having indigestion and mild nausea, no pain. that went on for several months. My doctor ordered general blood work and tests specifically for the liver and pancreas. He also ordered an ultrasound. The blood work was normal. The ultrasound only showed a mildly enlarged common bile duct, but within normal limits. I did not have any stones. After Protonix failed to ease my symptoms, I went to a GI doctor. He ordered an endoscopy and a HIDA scan. The ejection fraction on the HIDA scan was 17% and so he wanted to have my gall bladder removed. The endoscope exam found moderate gastritis and a mild hiatal hernia. The burning pain in the center and left of center which bored through to the back started just about the time I had the endoscopy. So the problem escalated from simple multi-hour tummy aches to actual pain. Nothing seemed to stop it. My appetite was pretty good though I found myself eating smaller portions and I lost a few pounds. No vomiting at all. After the gall bladder was removed on Feb 12th, I had a few days where I didn't feel too good, but now I feel pretty good. I still have some pain on my right flank back where the kidney is...not sure what that is. I have had some of that harsh pain in the center and left abdomen since the surgery but it only happens at night. Before it was happening night and day. The Pepcid AC seems to help that which makes me think it is due to the gastritis. My pain often hits around 2 or 3am when I am sleeping and then lasts until I get up. Before the surgery, it would last another 5 or 6 hours after rising. It hurt so bad that I went to the emergency room on Feb 3, heart checked out okay, sent me home with no diagnosis. I will see my GI doc again in early March and I will query him on my gastritis and any remaining symptoms at that time. The surgeon told me my gall bladder was enlarged and had adhesions which was almost certainly due to the fact it wasn't functioning anymore. I believe that it will take a few more weeks before I really know how I am doing. I am surprised your doc didn't order an ultrasound to check for stones. It is a much less expensive test than a HIDA scan. I don't believe the HIDA scan is good for diagnosing stones. You are probably doing the right thing in having your gall bladder removed as a result of the poor ejection fraction. It can only get worse. When you and your husband go see your doc, write down the questions you have so you don't forget to ask them. I often go in with the questions in my head and then get sidetracked and forget to ask them all. Oh, I did start getting some right upper quadrant pain shortly before my surgery. I was almost glad as it validated the diagnosis. I am still not absolutely certain what this left side pain is all about. Ask your doctor if there is anything you can do for your pain, perhaps a prescription pain killer, to get you by until your surgery in March.
