3. A burning sensation
An ulcer essentially burns through the wall of the stomach, and as it does, it can cause a painful burning sensation. At first, the pain may be dull, but as time passes, it will intensify. It might feel like a sharp, shooting pain in the upper portion of the abdomen, right where the stomach sits.
The pain will also increase during and after eating. Again, that is because the digestive juices are activated while eating and will make contact with the site of the ulcer. The pain may also be more severe when the stomach is empty.
