<s>[INST] I keep getting stomach pain aim the evening at around 8.00pm. The pain is so bad that I have to curl up into a ball till it goes. I get all hot with the pain. It doesn t last very long around fifteen min to half an hour. It goes on its own I don t have to take anything to make it dissapear, do you have any idea what could be causing this? [/INST] Hi, It can be due to many causes sic has peptic ulcer whose pain is aggravated after meals. It can be due to Renal colic whose pain is localized to lumbar region and radiating to the groin. If u have any Symptom related to urination such as burning micturition or increased frequency or else you should have an ultrasound PUB with full bladder for any obstruction and urine R/E for any infection. If the pain is localized to center of the belly You should have and Ultrasound abdomen to rule out other causes of abdominal pain such as stone in the gallbladder or other causes of pain. It may be due to after taking food that is gastritis you can use Omeprazole for that that is antacid. I hope I am successful in solving your query If u have furthered you can ask me Get well footage care </s>
