According to The Sun:

TEN people a week in Britain are hospitalised from playing Wii games.

The growing toll has prompted NHS doctors to warn of the dangers.  Wii-itis sufferers usually have excruciating pain in the right shoulder or knee.

Dr Dev Mukerjee, of Broomfield Hospital, Chelmsford, Essex, said: “There has been a 100 per cent increase in patients complaining of Wii-itis.  “I’ve seen many patients aged between eight and 13 — and I’ve seen adults.

“It’s possible that Wii-itus may lead to rheumatism and arthritis in later life. Patients often have inflammation of the shoulder or wrist.”  Others have a ligament injury dubbed Wii-knee which some have blamed on the popular Wii-Fit game.

Dr Mukerjee said: “People who are double-jointed are most likely to suffer from Wii-knee — and in extreme cases the knee cap can be dislocated or can even pop out.”  Treatment includes cortisone injections and anti-inflammatory painkillers. Recovery takes up to three months.

OMG how dangerous!  A 100% increase (from 5 to 10 people per country per week)!  You could have rheumatism and arthritis in later life!  Wii-knee!  Cortisone injections!  Painkillers!  Those are addicting!  I never knew… I never knew…  First we find out that playing games was addicting, and now we find out that the injuries suffered through play could be life-altering!  And we find this out right before Christmas!  Just think of all those torture machines that are already wrapped and under the tree!  Oh the humanity…
