My friend what you are having is called as post prandial angina and you should get yourself thoroughly is evaluated by a cardiologist as soon as possible this can be an early sign for an impending heart attack in near future Get immediate medical care if you have chest pain that does not go away, crushing pain or pressure in the chest, or chest pain along with nausea, sweating, dizziness or shortness of breath. Treatment depends on the cause of the pain. To rule out cardiac issues. Get a ECG and 2D echocardiography done. If they are normal then get a Stress MPS done
