<s>[INST] I just got back rom the e.r yesterday because for about the past week now I have been having severe pain on my right abdominal (side stitch feeling) and back. At first I thought I had appendicitis because the symptons I had were similar. It hurts to take a deep breathe and the pain is unreal. It feels better sitting down hunched over. The doctor gave me an ultrasound, and an xray which botChatDoctore out normal. So he did some bloodwork and that came back positive. I was then given a catscan but that was normal. The hospital discharged me with some narcos and motrin, which neither of them seem to help. The pain is agonizing. What could possibly wrong? [/INST] Hi. Sorry to know that you have not been diagnosed and your visit to ER went fruitless. The history you have given is very catchy.... It hurts to take a deep breath = and feels better on sitting down hunched over. The cause of pain in your right abdomen and back together can be due to an inflammation of the retroperitoneal structure like the kidneys, pancreas and so on. I would advise you the CT scan of the abdomen. Normal X-ray and ultrasonography have their limitations in finding out many problems hence the need for a CT scan. You have not mentioned the positive blood reports. Get serum amylase and lipase too done. If the pain is agonizing I would suggest you to visit ER again and get further tests done. A proper treatment depends upon the correct diagnosis. </s>
