I had some significant hand and wrist pain Saturday morning, then took the whole day off from typing and other hand stuff, except for playing a turn-based game on the Switch for 20 minutes.
Sunday, there was still some sensitivity in my hands, but I was mostly OK, so I took a risk and worked out and recorded a guitar part, which amounted to maybe an hour of playing, though not continuously.
Today, I’m mostly fine, so guitar playing (to an extent) isn’t the hand-destroyer that I thought it might be. Shoveling (at least the way I used to shovel) and typing for long periods are what I need to look out for, I think.
