Unexplained wrist pain?

This morning I when i went to work I began to fell a pain in my wrist. It's on the outside of my wrist and can be felt from just below my pinky finger to about an inch below my wrist. Most of the pain is centered on the wrist itself. I don't have a constant pain it's more like a sharp stabbing sensation when I twist it or move my wrist while grabbing something. Also trying to grab something that was wide, while I had my palm facing down was quite painful. I haven't had any type of injury recently, outwardly it looks fine(no bruising or anything like that), and yesterday it was fine.
