Sir. Many times after I drink water or eat something, I get sudden sharp pricking pain in umbilical or just right to the umbilical. If into something, it takes 30 mins for the pain to occur and it lasts for only 1 second. The pain lasts for 1 or 2 seconds only. What is this? I have history of peptic ulcer (duodenal ulcer) and gastritis since three months. Having ibs too. My stools are normal, blood levels normal. Kindly help sir.
