I think I broke my thumb

You know when you start a new work out routine and you have muscles that kill you because you never use them? This is now my pain. I think I have sprained my thumb muscle. How does one do that? I will tell you..... You pull your pants up and down 80 times a day to pee. Stop laughing....it hurts! I can barely type. Someone should come up with a list of crazy ridiculous things that happen to you when you are pregnant that no one ever talks about. I never read that a possible reaction to pregnancy was a broken thumb from peeing so much. It happens....it really does.
