Burning pain in stomach, below your breast bone, felt on contact with food, leading to nausea, vomiting, feeling of fullness, belching and heartburn, may indicate presence of peptic stomach ulcer.
Helicobacter pylori infection is usually associated with this condition.
Course of antibiotic treatment would be helpful.

Talk with your physician!

that could definitely be an ulcer. H.pylori is often associated with ulcers (as the person above me mentioned), but that's not always the case. Your doctor can do a simple test to see if that's part of the cause, and a 3 or 4 drug course generally takes care of it.

What pills are you taking?
