<s>[INST] I have a gnawing pain in my stomach that occurs after eating. I've had an endoscopy, ultrasound, and hida scan that all came back normal. I was diagnosed with ibs. After making lifestyle changes, the pain is still there. Could this pain be a sign of something else like hiv? [/INST] Hi there,No this pain is not because of HIV, it may be due to gastritis, ulcer in stomach, or infection in stomach, or even after food there is stretching of stomach which causes temporary pain, welching,burping,bloating..etc.Regards. </s>
