Pfft, I heard that; I've met over fifty doctors in my lifetime, and I found I could count the number of competent and compassionate ones on one hand and still have enough digits left over to pick my nose and insult someone's mother.<br/><br/>I think the term for what youre describing is hemoptysis, mate. If it presents with chest pains, tell your doc to check your blood gases and do a lung scan. At the very least, get your bloodwork checked and rule out any infections. If your insurance will cover it, you  might want to ask for a chest MRI as well, if they havent done one recently. (note: *IANAD, *YMMV, etc.) Just stay safe, amigo.<br/><br/>*I am not a doctor.<br/>*Your mileage may vary.
