Any tips for preventing/managing wrist pain from writing?

This happens to me every so often when I paint or handwrite things daily, or even just from typing. I get what feels like nerve pain that starts in my wrist and goes all the way up to my elbow.

I'm not sure if this is just like a personal problem or what haha, but I wanted to see if you guys have the same issue!

It'll go away on its own eventually, but it takes a while--at least a week, typically. It drives me crazy, though. Any tips? I'm desperate!
