I seem to be suffering from emacs pinky syndrome lately-- the third joint of my little fingers, where the finger connects to the hand, is perpetually sore, and when I wake up in the morning my little fingers are tingly and slightly numb.
The funny thing is, I don't use emacs. Still, I'm becoming conscious of how I type, and I do notice that I'm pulling my pinkies around quite a lot. I'm a little sloppy about how I use shift keys, and I'll often twist my hand around so that I can hit the shift key with the same hand that I'm hitting a letter with. Clearly, That Shit Must Stop.
I also bought a home paraffin bath yesterday. I've wanted one ever since I was seeing a hand therapist back in the mid-90s after a car accident, and she told me to go dip my hand in the melted wax ten times. I'm sure my look of astonishment was very similar to the one that most of her clients gave her, but it was for an entirely different reason. Anyway, I wallowed in hot wax last night and it made my hands feel better for a while, but it doesn't seem like it will be a solution.
What else should I be doing? I've always avoided comfort keyboards, but now I'm wondering if using one would make a difference. Other suggestions?
