Since you are overweight, control your eating habits stop taking junk oily food. Cut on salt intake. Take fiber, calcium minerals in your diet. Stay away from addictions if any. Visit ER, get physically examined, get CBC, Lipid function test, Urinalysis, X-RAY, Echocardiography, Stress test is done to rule out any developing coronary artery disease. Your treatment will depend upon the pathology detected. You can take PPIs, Omeprazole AcetaminophenTylenol for pain. Hope I have answered your query. Let me know if I can assist you further.
