I can get used to a pain and touching it doesn’t really help but an itch oooh boy drive me mad, probably because I knew it’ll feel so good in the short term at least!

There have been people with persistent itches that scratch, sometimes subconsciously, in their sleep, etc, until they hit bone or an internal organ, or both, like their brain: https://www.npr.org/2008/06/24/91852486/the-mystery-and-powe... The itch-scratch reflex is mighty powerful.

Yeah, nope, I read that years ago and it’s still one of the more horrifying things I’ve read.

I suddenly became itchier than I can recall in recent memory. Thanks.

Yes indeed that was what I was thinking about, that type of case. Literally itch through your skull in the right circumstances and it sure isn't will power.
