<s>[INST] Hello, I have been having intermittent, crampy pain in my upper abdomen ever since I had an EGD with biopsies of my esophagus, Antrum, and duodenum. The procedure was five days ago, and while the pain hasn't worsened (and certainly isn't intolerable) I'm wonderiing if this is common, and also curious as to what might be the cause. Thanks. [/INST] Hi and welcome to HCM. There are many possible causes but most common are gastritis, GERD, gallstones or IBD. When you rule these out then some more serious diagnosis should be considered. YOu should change your dieatry and lifestyle habbits and see will it improve. This is the best treatment. Also you should take some antiacid medicines. To check your liver,gallbladder and pancreas you shoulds do abdominal ultrasound and then plan further tests. Wish you good health. </s>
