I am facing this issue from last 17 years. I am 40 years old in a perfect health otherwise with doing exercise, dance regularly. With no apparent reason, All of sudden my tummy start hurting( in the middle) and keep coming and going every 2-3 mins. This pain is unbearable and last up to 30 hours where I can not eat, throw up and finally it recedes by its own. I had every possible test from many Internal Medicine doctors like Endoscopy, CT Scan, X Ray etc but no one is able to diagnose why this happens and what is the cure? Sharing on this forum in case anyone has faced similar issue
