regular use of thumb. I don't use the thumb to wrap around and play notes, it's just against the back of the neck. But playing chord melody usually involves holding chords for long periods of time which is quite hard on the thumb which counters all that force.
My issues just came about during jazz chord melody as my 25+ years in rock soloing didn't usually cause issues. So like others it's mainly an overuse problem hopefully, however I have taken a week off here and there recently and it had no effect.
I'll be doing some physio soon as I noticed lots of sore spots even in the forearms and I've done some reading on trigger points, etc.
