Hi Dear , As per your query you have severe chest pain after eating food . The symptoms you mention in query are pointing towards a condition known as acidic reflux or gastrointestinal reflux disease . This condition occur when upper sphincter of esophagus fail to hold the acidic content of stomach and it come upwards due to its dysfunction . In this type of condition only medicine is not going to work , it also require lifestyle changes . I would suggest you to avoid eating spicy and heavy food specially at night , take small and frequent meals , avoid caffeinated products , take light walk after every meal and continue taking medicine prescribed by doctor . If condition doesn t get improve then consult doctor again for proper examination . Doctor may recommend surgery to correct then condition or refer you to cardiologist . Hope your concern has been resolved. Get Well Soon Best Wishes, Dr. Harry Maheshwari
