What Is The Treatment For Severe Wrist Pain?

Okay, so I randomly (nothing different in my routine) got a terrible wrist pain. It kills when I put pressure below my wrist on the top of my hand (not palm) It also hurts to rotate my wrist to the right but hardly hurts at all when I rotate it to the left. What could be causing this? I don't remember hurting/straining myself.. I don't do anything involving my wrists alot (a little typing, but not a lot)

This has been going on for 3 weeks now.. and it's not getting any better. Suggestions before I head to the doctors?
