Pain In Chest Area ,behind Solar Plexus Area... It Forms

Pain in chest area ,behind solar plexus area... it forms a hard bulge just below my ribs, feels like I want to vomit everytime I eat ... pain has been getting more severe over the last 2 days and at times radiates downwards and outwards in my abdominal area. I eat only a small amount at a time and it still makes me uncomfortable. ..also extreme amount of burping (for me ) ....
