Has anyone else had this problem? It used to only happen when my father was eating, but now it happens every once and a while when he isn't eating. He has been diagnosed with Parkinson's for about 8 years now. The symptoms have gotten a lot worse this last year. It is very scary when it happens. He can't breath at all except for gasping for air. He has even started turning blue one time and I got so scared. It usually last for about (seems like forever) 30 sec to maybe even a minute.
