When you wake up in the morning, do your knuckles click between positions? For the first minute or five after I wake up, always the ring and little, and sometimes all four, fingers on both hands will want to be either flexed most of the way (as like making a fist) or mostly extended, and moving them between the two points, they'll resist slightly, then click over to the other position, refusing to stay in between. It's just the main (palmward) knuckle, not the others. It's not like an audible click, just a.. like a toggle switch, that doesn't want to stay in the middle position, but will flop one way or the other. Does that make sense? It's not painful, and it goes away quickly. It's just a kind of stiffness, and it works itself out.
Is there a name for that?
Like I say, it just works itself out. Except, recently, for my right middle finger. For the last month, month and half, it keeps behaving like that for a while, half an hour or more, and at the start it's difficult and painful to extend. I can use my thumb and push it open, and that works, no difficulty. It's only when trying to do it under its own power, as it were. And as time has progressed, it's gotten to the point the middle joint is doing the same thing, and will continue to do so for a good chunk of the day.
More recently, like the past couple days or so, it's been painful to extend the finger, even after getting past the click.
Today was particularly bad. It hurt to unbend the finger, hurt a LOT to extend it fully. It's evening now and it still hurts to flex and extend the finger. Most of the pain localizes to the middle joint, but there's a decent share for the main knuckle too.
I've been trying to reduce use of the right hand, and especially that finger, but since I spend most of my time at a keyboard, and the right middle finger is in the top 5 fingers I use when typing, it's kinda hard to do that. I never did get the hang of my one-handed keyboard. I've also been trying to stretch the connected muscles out, but it hasn't had any noticeable effect.
I'm seeing my doctor on wedesday. (Probably for the last time, as he's retiring. This is only the third time I've seen him, which is sad. Time to pick a new doctor /again/.) I'm just seeing him as a regular checkup, but will be bringing up the finger thing.
Given that my mostly-awesome Popcap-sourced insurance ends at the end of the month, and my new not-remotely-awesome Lifewise individual plan starts, I fret that this is going to end up requiring surgery.
