What is a good way to determine if you have a stomach ulcer?

Pain: Burning pain is the most common peptic ulcer symptom. The pain is caused by the ulcer and is aggravated by stomach acid coming in contact with the ulcerated area. The pain typically may be felt anywhere from your navel up to your breastbone, be worse when your stomach is empty, often be temporarily relieved by eating certain foods and disappear and then return for a few days or weeks.
