The Wii was one of the hottest buys of the holiday season. In fact, some people are still on the waiting list. But among those who've been swinging, bending and twisting with that interactive video game, there is a new frustration called Wii-itis.
That's the name of a new illness coined by the New England Journal of Medicine. It is what doctors describe as a sort of tendonitis or tennis elbow among Wii players who don't know when to quit.
Even so, most health experts are applauding this game for getting people of all ages up off the couch and into some activity.
So what do you do for Wii-itis? Therapists say quit playing for a while and apply ice if there's swelling.
