I stretch out my wrist, hand, and fingers using stretches to help with carpal tunnel (which I have).
I also wear a wrist splint at night, take breaks, wear a different wrist splint that has more room for my fingers to move and I draw while wearing it.
If it’s too bad I just stop for the day.
But yeah take care of your hand and wrist, I got carpal tunnel pretty quickly and my hand is hurting slightly almost all the time now. My grip has weakened a bit (tho I’ve always had an iron clad grip so I’m still okay). Sometimes my fingers start tingling. I feel numb around my wrist and hand. I get tingling up my whole arm sometimes. It can be incredibly painful. Also if I hold things at certain angles my hand goes numb.
I’ve just lived with it for a few years now so I’ve adapted to it and I’ve always been able to ignore my usual pains since I’m pretty much always in some sort of pain. But I’m lucky cuz I can still grab stuff. I’ll be up a creek without a paddle if I become unable to grip stuff.
Anyway you get this from doing repetitive motions everyday. That’s why breaks and also wrist splints are great. At night wearing a splint helps cuz you never know what weird way your wrist and hand will move during the night and just stay that way and it puts unnatural and unnecessary strain on it.
Also I wrap makeshift pencil grips around my pencils. I tear off some paper towel strips, wrap it around, then over that I wrap a large rubberband where I usually grab my pencil. You could use other pencil grips but most of mine come with built in grips that just ain’t big enough so store bought grips wouldn’t fit. Plus with rubber bands you can make it as big as you want.
It helps a lot.
