How would i know i have a peptic/gastric ucler?go away on their own? stomach discomfort after eating, no burning or pain, just gnawing, no bloody stool

Maybe: May be gastritis or inflammation. If it is, it can progress to ulcer. Medications such as antiinflammatories and antibiotics can irritate the GI system. Consider a bland diet. Avoid spicy and tomato or acidic foods. Avoid nsaids unless absolutely necessary- if so, take with food. Consider otc ranitidine. If persists/worsens, see your physician.
