I remember practice for long periods at a time. My hands would start getting arthritic and small little soars would start popping up.

I just gave it a little massage and everything was okay.

Don't overdo things. When you hear stories that musicians practiced for 8-10 hours a day, that's a load. 

The human mind and body can't comprehend that much intense focus. You have to be some type of savant. I'm sure they had plenty of breaks in their day, but never 8 hours straight for years, that's insane.

It's important to always take a break and relax your hands and mind.
