I just experienced the same thing with my boa, the best thing i can tell you is to get it to a vet asap. Miranda (my boa) had an RI and is still recovering. But the antibiotics that the vet put her on worked wonders.
Is your little guy showing any other signs such as open mouth breathing, bubbles arround the mouth and nostrils, or tilting its head back to breathe?
I was handling my male Bp today and i noticed alot of wheezing , all temps are normal what do you guys think.
If he is in fact wheezing, your temps are not normal.
I'd start looking for a vet.

i posted a couple days ago that i noticed my BP weezing, actually it was more of a whistling sound. but after about 5 minutes she stoped and i havnt heard her sense. i was very worried at the time, if your snake is still makign these noices i would get it to a vet. i was going to take my BP but everything seems to be fine now. some said it could have been a loose peice of skin from her previous shed in her nostril.
