Recently I have developed a feeling of my heartbeat in my throat,,,,it like seems to beat the stop for a second and restart with a thud in my chest and throat....I also have at times a hacking dry cough....I am an alcoholic that smokes and am getting worried that poor lifestyle has finally taken a toll on my health and heart....I have no health insurance and now live every minute worrying if I am going to just drop dead.....please help!
