Quick pomodoro style timer so you hands get a rest interval.
This is a tool but not a cure. Physical therapy with an specialist can give you a window of time where you are free of pain. Then exercise is the long term solution. I am following this path, ask me in 3 years if it worked :-) .
It should be pretty self explanatory on how to use. If you have mpv
installed on your PATH you will also get a ding sound when the timer goes
off.
