I love school, typing not as much.

My right wrist has been killing me because between school and working at Target as a cashier it does not get a break at all! typing is not a one hand thing to most people because most people are taught the correct way to type, which I admit I’m using right now to a certain extent, and don’t try anything else. my counselor once caught me using this method and was amazed (for some reason) that I could type that fast with only one hand while I was flipping through notes with the other. I now realize that writing in pen and pencil could also be a problem because of always using one hand so I’ve been doing 3 things that can cause this so it’s probably a good Idea to see if there is any good way to fix it. has anyone else had any problems like this?
