Hello, @emiliaparker!
I suffer from Carpal Tunnel Syndrome in my right wrist. When it flares up, due to over activity, typing can certainly become uncomfortable. CTS is a relatively common condition that presents as pain, tingling, or full numbness in the hands and arms caused by the nerves running along the arm being squeezed. Whenever I can start to feel a flare up coming on, I simply wear a wrist brace for a few days. A metal bar in the brace keeps my wrist in a neutral position. Giving my wrist a break from movement for a couple of days always seems to take care of the problem. I’ll sometimes wear the brace preemptively as well, if I know I will be moving my hands and arms a lot, like, if I know I’m in for a long day of typing.
Hope that is helpful!
