<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 27 year old male and I have been experiencing sharp chest pains and difficulty breathing for about 2 weeks now. I am a smoker, 510 and 197lbs. It feels like the pain is in two different spots, between my breasts and in my right armpit. Coughing feels like Im having a heart attack and most recently, I have seen changes in my stool color to a bright yellow. I have decreased the amount of cigarettes I smoke down to one a day since this started but have seen no improvement in the pain or labored breathing. Please help.
