Pain in my chest and spitting up blood???????????

Did yo spit it up or puke it up? I am sure you are an intelligent person, but if yo want a mor thorough answer, you must provide more info. Do you have a cold? what were you eating? are you an alcoholic? pancreatic cancer, esphogeal varices, ruptured aneurism, emphysema? blooody nose running down yor throat? Pneumonia? How about pulmonary embolism? If you don't have a clue, go to ER. If you are retarded, go anyway.
