<s>[INST] I have been having attacks after eating in my middle back. Sharp pains. About 15 minutes after eating. Had Gall Bladder removed. Did not help problem. I get these terrible attacks at night while quiet or sleeping and they can last for an hour or more. The pain is so intense, I break out in sweat. very very painful.  So it is not always from eating. what could be the cause? [/INST] Hi, the gastric pain associated with the gallstones is a symptom complex, and after removal of the bladder also you need to use medicines for gastric pain, for some time depending upon the severity of the erosion.                            I to my patients with such pain prescribe omeprazole, domperidone, and antacid gel for one month.                            Avoid taking spices, junk foods, and oily foods. Thank you. </s>
