I don't really know what you mean when you say 'blowing her throat up'. One of my
Children's pythons developed a swollen throat quite rapidly. I fed him and the swelling disappeared almost immediately. I put it down to oedema of unknown origin. I know of someone else who had an experience like this. If there's a wheezing sound as she's breathing, it could be a respiratory infection (as suggested above). Taking her to a good herp vet is definitely the best action. The "Protazoan infection or she is doing it as she has started eating bigger prey" opinion makes no sense to me at all. If it is a respiratory infection, it's most likely bacterial, but possibly viral or fungal.
Good luck with your snake (and let us know what happens),
Stewart
