That stinks! Sorry you are dealing with this. It is my understanding that severe abdominal pain in the area you describe that goes away after eating is most likely an ulcer. In fact, it's the hallmark sign of a peptic ulcer. There are other symptoms too but you have the main one. Since this has been going on, it might be a good idea to see a gastroenterologist. Your doctor put you on a proton pump inhibitor which can be prescribed for acid/gerd. But ulcers are a bit different. They can be caused by things like H pylori which I'm sure you've heard of. They treat the H. Pylori and you are on he road to recovery. There are other reasons people get ulcers too. The doctor can rule those out best. Peptic ulcers can be in the stomach or in the intestines called a duodenal ulcer. I have had one of each (lucky me). Sometimes they will do an endoscopy to find the little sore in the lining and sometimes they will just treat for it. Here's info on peptic ulcers. https://www.mayoclinic.org/diseases-conditions/peptic-ulcer/symptoms-causes/syc-20354223. I suffered my first ulcer for several months before it was found on endoscopy and then I drank a chalky liquid for two days and felt better. So, it can be a quick recovery if this is the situation for you. Do you take a lot of nsaids by the way?
