Nine-fingered Doro and the Data Entry of Doom
I find that I’m typing with nine fingers these days, because if I give my left littlest finger much of a workout it starts to spaz.
Best I’ve ever been able to figure is a case of cubital tunnel syndrome, with entrapment at the wrist rather than the elbow. I have been careful about sleeping with bent arms lately. Not sure what else to try that I’m not already trying.
