For The Last 2 Months I've Been Experiencing Chest Pain.

For the last 2 months I've been experiencing chest pain. Nybheart feels like its being crushed in the process as my chest tightens up my breaths shorten and every breath after that follows with a sharp pain. I feel pain in NY back as well and this morning I started coughing up black mucus and little bit of blood. I've been smoke free from ciggerettes for over a year.
