It used to be that the only injury you risked sustaining playing video games was sore thumbs. But a doctor who recently woke up with a sore shoulder diagnosed himself and coined a new term: "Wiiitis." The Nintendo Wii has a new tennis game in which players simulate actual tennis moves. The difference is that, in Wii tennis, you don't have to run up and down a court, and the game can literally be played for hours. That can lead to a repetitive use injury in the shoulder.

Luckily, the injury doesn't seem to be severe and Dr. Julio Bonis -- the doctor who named the injury -- recommends ibuprofen for a week and a break from your video tennis habit.
