Is this Scale rot?

[Fuego]

Hi, could anyone tell me if this is scale rot? I just noticed it on him while handling him and its the first time I'm seeing this. It's a little bump and feels dry like a scab, could it be just a abrasion from nose rubbing or a wound from prey? I feed him live mice but so far I haven't seen him sustain any wounds nor the rat managing to get close to his head while he's constricting but I'm fairly new to this so any advice would help

I noticed there was some black gunk in one of his nostrils as well but its pretty in there and I can't get a good photo of it

Top pic looks like old stuck shed. If the spot doesn't clear next shed then keep an eye on it.

Agreed, just keep an eye on it until next shed.
