The thought of wearing a radiation mask is absolutely terrifying to me. Not only from feeling claustrophobic, but also the fear of choking on my own saliva/secretions. I have persistent post-nasal drip and I can not go for longer than about 30 seconds without having to swallow - especially when lying down. Can you swallow with the mask on at all? Especially a mask that covers the throat area as well as the head? For those that have also had to wear the mouth-piece, how did you do without being able to swallow with that in during treatment or not gagging on it?
