White spots and "wierd" behavior

[guidofatherof5]

Glad it's gone.
Blisters don't just disappear. Many times they will even leave a scar.
I'm glad this worked out well.
Better safe than sorry. I'm glad you posted about the situation.
It sounds like your snake is in good hands.

Could there possibly be sharp edges deep inside that log? I still fail to see why you cannot plug that hole...you can plug a doorway with expanding foam lol

it didn't look like a blister to me - they tend to stick out more
but I couldn't figure out what it was beyond that
frankly, looking at the photos, it looked like a paint spot, and that didn't seem likely
now, that it's come off I wonder whether it was a urine stain

I've seen this on Mama. It ended up being some poop. She always poops on her head, or Snakey poops in her head. Either way, her nickname isn't Poophead for nothing.

I can't plug it because it's not just a hole and I can't get to it!!!!
If you could see it you would understand.

I've got a piece of wood with one of those
in my case it's a large crack where a branch comes out of the main piece, and I never use that piece in enclosures with animals that are small enough to get in there
