Hello, Thanks for the query to H.C.M. Forum. If I were your treating doctor for this severe pain in the stomach, I would come up with these possibilities , these includes. 1 The first possibility is of acute gastritis ( because as you mention that this is a recent pain ) . Diagnosis can be confirmed by upper G I endoscopy , visualize erosion of gastric surface of stomach. Try raising the head of bed 4 inches above with blocks. It might also help to avoid eating or drinking 2 hours before you lie down. To help control stomach acid one should not drink alcohol or drinks with caffeine in them Avoid fried food , spicy food. Take some antacid , but if symptoms are severe you may need proton pump inhibitor. 2 Next possibility may be pancreatic cause , serum amylase and lipase enzyme examination will find out any disease. In my opinion consult a physician and get his opinion. Good luck. Dr. HET
