I have been having chest pains for about a year. I have hypertension which i take meds for. I am overweight. I have been to the E.R. many times and they always say im fine. Ekg, blood tests, chest xrays. They send me on my way like nothings wrong. I recently have been having what they think are panic attacks. I dont get to where i cant control my breathing (hyperventalating) i just get extremely fast and hard heartbeats and fear im going to die. I need help please.
