I get a really bad pain in my right abdominal area during exercise. It can occure from just going on a short walk, and is so bad i have to stop which makes it go away instantly. I have had it for about a year and have seen 3 doctors who cant find anything wrong. One suggested it may be a traped nerve. It is always worse when i have not eaten, and seems not to appear if I have eaten before. I have done some research and notice that gastric ulsers cause a pain similar to mine, and also don't cause pain when food has been eaten. My pain is only there during exercise though? Any help would be appreciable. Many thanks.
