Snake whistling when she breathes

[StellaDoore]

Okay, have had a BHP for a month or so now. She's 2 years old, 6 feet long. Has had 2 very successful feeds (absolutely no problems) and has just finished shedding (about a week ago).
However, I've noticed that occasionally when she breathes a faint whistle accompanies it. Kind of like when a person has a partially blocked nose, which whistles softly when they exhale.
Is this a problem? What should I do about it? I hope I'm only being paranoid but it certainly doesn't hurt to ask and figure it out early.
Thanks for the help everyone!

there are many things it could be
So sweat it too much
Often a small piece of retained shed can cause this
One other possibility is a slight respiratory infection
Usually you can hear the infection in the snakes chest/lung area
Just keep it warm and an eye on it
