I am 35 y.o. female. When I was 10, I was diagnosed with chronic pancreatitis. I had epigastric pain. I had elevated levels of amylase and I also underwent function testings. My family has no history of chronic pancreatitis. I was treated successfully, was on a strict diet for a couple of years, and then I was symptoms -free for years. Occasionally, I would have periods of mild epigastric pain, they would do ultrasound for my pancreas and see no abnormalities. About two years ago I suddenly developed pain in my back (where the left kidney is). THe pain was dull and very persistent. I went to see a doctor. He ordered the ultrasound of the left kidney. It was normal. Meanwhile, the pain relocated to the upper left quadrant of the abdomen and the left side of the body. It was aggrevated by food. I told my doctor about my chronic pancretitis diagnosis at age 10. I then underwent 2 abdominal CT scans with contrast (with a 6 month interval between them), gastroscopy, MRI of the pancreas, 3 blood tests for amylase and lipase, gastric emptying study, X-ray of the intestines, and H.pylory test. They did not reveal anything abnormal. I tried prilosec, antispasmoid pills, and paxil with no improvement of my pain. The doctor told me that he does not see pancreatitis and also that I do not quite fit the profile for IBS. After more than a year, the pain disappeared for several months. Two weeks ago the pain came back for no apparent reason. It is mostly in the back (the same spot - the projection of the left kidney), sometimes it goes higher (just below the spatula). Sometimes the pain is in the left flank. I have mild pain in my epigastrium also. The pain is clearly aggrevated by food (any food, it seems to me). I noticed also that now the pain is more severe when I lay down on my back (I feel burning pain in the back at my waist that irradiates to just inferior to the spatulas). Sitting up somewhat releives my pain. This is a new symptom for me - before the pain would not intensify when I would be laying down on my back. I do not have nausea/vomiting, and I do not have diarrhea or constipation. The pain is very persistent, and I am very afraid that my pancreatitis came back after so many years. I am hesitant to call my doctor this time, because he told me last time he saw me that he could not find anything wrong with me. My husband tells me that I cannot have pancreatitis, since all the tests were negative. I want to beleive this, but I read in the literature that CT scan and MRI are not very reliable in diagnosing early or mild pancreatitis. I am especially upset now that the pain gets worse when I am laying on my back (this interferes with my sleep), which is, as I read in the literature, is a characteristic symptom of pancreatitis. Is it possible that the cause of my pain is still a chronic pancreatitis (despite all the negative tests so far) or can it be something else (I do not have a fever or some urinary problems)? Thank you! PS. I do not drink.
