Hi, As cardiac enzymes were within normal limits and blood pressure as normal, thus following is my opinion: - One has to exclude GERD [gastroesophageal reflux] as the first diagnosis of exclusion since most of the time patient is suffering from the same and it does give rise to chest pain, gas and cough] - Or it could be because of a pleural pathology. Thus, check with a medicine specialist for endoscopy and X-ray chest. - It could be stable anginal pain, so check with a cardiologist for an electrocardiogram, stress test, an angiogram, and investigations like lipid profile, blood sugar and make sure to reduce weight [if overweight], avoid sudden exertion. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Munish Sood, Ayurveda Specialist
