Hello there. It's unfortunate that you are in pain. Here is what you can do. 1. Drink lots of water. 2. Avoid oily and spicy foods. 3. Avoid having large meals, have smaller meals at regular intervals. 4. Don't sleep immediately after food. 5. Sleep with a head raised a bit. If it still persists, you can consult any general surgeon, you need not consult a gastroenterologist. Regards

Hi If it's just for the first time you can consult physician .... Avoid having spicy and oily foods, drink excess of Water and fiber rich diet.... If it's recurrent you can consult Gastroenterologist...
