Hello, What you re experiencing is not likely a heart attack. It seems to be more of an electrolyte imbalance probably low potassium. Typical of heart attacks would include chest pain substernal in nature with crescendo-decrescendo pattern with radiation towards the jaw and left arm. This could also be associated with heavy sweating and a fast heartbeat. most people would have a feeling of impending doom . On top of all this, you should have risk factors for a heart attack such as hypertension, diabetes, or illegal drug use. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Chuckie Miguel Bacolod, Internist / Hospitalist
