Don’t assume that the burning sensation between your belly button and breastbone is heartburn; it might be an ulcer. A crater in the lining of the stomach or part of the small intestine that develops because of an imbalance of digestive juices is called a peptic ulcer.

Reportedly, over four million people in the United States suffer from peptic ulcer disease each year—meaning about 1 in every 70 people are battling the condition at present. Though an ulcer is capable of causing a great deal of pain, at times it will manifest no signs or symptoms. If not treated promptly, these small defects in the lining of the stomach or small intestine can result in major damage, including perforation and bleeding.

Take a look at these 10 warning signs that are indicative of an ulcer.

1. Dull Pain in the Stomach

A feeling of discomfort in the area between your ribs and the navel may be felt if you have an ulcer. The pain in the pit of your stomach can be extremely agonizing after meals when the stomach empties. In many cases, the stabbing pain keeps coming and going spontaneously in frequent intervals. The symptom can be promptly relieved by simply consuming foods having a neutralizing effect on the stomach acid.  Be aware that gas or constipation can also be a possible reason for a dull pain in the stomach.
