"Wheezing" during shed?

I noticed my male Pastel was making some wheezing/whistling noises while he breathed the past couple of days and initially thought he may have a respiratory infection but he shed out this morning and the whistling noise has since vanished. Still keeping an eye on him in case it comes back but has anyone had anything similar happen before?

He probably just had a loose piece of skin in his nostril, which shed off with the rest of his skin.

Yep, that ^
