I have a teenage son who has this strange condition,he has asthma but everytime he sneeze's or laugh's to hard he starts chocking and goes into a severe asthma atack. He is fighting to breath as he use's his neublizer machine, sweat is pouring down his face and he some times turns different shades of red and purple. We recently say a pulmanary specialist, he changed some of his meds and he said that he thinks maybe his vocal cords spasm when he sneeze's-that is why he can't breath, Is there anything you can do for that? Has anyone had this that can give me advice, We go back to this doctor in a month,we have seen many specialist, no one has been able to help us. Thank You, Karen W.
