hello, ive had my ball for two weeks now and while trying to get the humidity in his enclosure to be high enough for him to shed i accidentally kept his substrate damp for about a day.
i fixed the issue as quickly as i could, and he's shed the day after, but he seems to have developed scale rot on just one scale on his belly, and it hasnt changed the past few days.

other than that, he also has developed these on his head, which is concerning me. its not a marking, but i cant tell what it is. im thinking it could be scale rot, but its... a strange place for scale rot.
any idea on what it could be?
this is the weird scales on his head:


this is the other side of his head:


this is the one scale on his belly:

he is active, he eats and poops just fine and his shed was good too.
