Is wheezing/squeaking always a sign of a respiratory infection? My snake Zeus has been making strange sounds occasionally, but he's trying to rub the dead skin off his head, so I'm hoping the sounds might be normal. I'm going to try to find a vet in my area who can see him, but in the meantime I need to know what to do. It's warm in his cage ... a bit humid outside lately, which may be affecting him, but I don't know what to do about that (can't afford to buy a dehumidifier at the moment).

He's never let me touch his head ... I've read that there's a way to drain mucus, but he freaks every time I get near his neck. There are no bubbles coming out of his nostrils, but there's some dead skin there that I can't help him get rid of. Please help if you can ... the sounds are really scaring me.
