For a few years now, my thumbs have occasionally seemed to suddenly bend inwards, and get stuck in a sort of spasm.
It's impossible to move the thumb back into its normal position unless I prise it with my "good" hand.
The last few weeks though, both thumbs do it, along with some of my fingers.
It's very painful- like cramp.
I'm not asking for a diagnosis, just wondering if anyone else gets it.
The whole outer side of my palm is now curling inwards, ouch ouch ouch!
