If you froze 3 or 4 fingers pretty badly and are having breathing problems but yet you will not see a doctor because you don't have insurance, well... pretty effing stupid. Cough up the cash and get checked out.
And no you cannot freeze a lung. Like others have pointed out. You would have to die before your lung could freeze.
