Read a darn book. 100 hours a week? Lately I can't manage 10 hours maybe not even 5. Priorities mad, priorites.

He died after his last post.

that's crazy. I only spend 20 a wk on gaming,on average.

So doctors are morons and he should listen to an 11 year old from Antartica :P.

If he is having problems with his thumb it is most likely related to impingement of his median nerve in the carpel tunnel.  Although there may be an inflammatory component it is a mechanical problem which will be you'll have about as much luck treating with oils or any other pharmacopoeia as you will trying to mend a broken arm with some smelling salts.

The long term effects of letting this go unchecked or continuing the activity which either caused or exacerbated the problem are a little worse than a little bit of pain in the wrist.  The long term effects could be; loss of sensation on the lateral aspect of the hand, loss of muscular strength and wasting of the thumb muscles, inability to grasp properly and ultimately deformity of the hand.  Not good if you are in any kind of job that actully requires you to use both your hands.

Does he need to quit gaming, probably no.  Does he need to cut down or quit for now, certainly.  Can there be more serious side effects to your health from gaming besides a sore wrist, yes, but I'd argue that loss of function of a hand is quite serious enough. 

Would you be willing to stand by your advice that his wrist should be fine if he 'only' gamed 30-40 hours a week and rubbed a bit of St John's and Lavendar oil on his wrist.....?  Of course you don't have to because you are just some guy on a message board but his doctor has to be able to stand behind his advice and he obviously thought, for now, that there was no safe level of gaming for young Blink182.

I know who's advice I'd be listening to ;)

p.s. although I could be totally wrong and it might have nothing to do with the median nerve :)

Oh, how I envy you.

what are you a doctor. lol

On a gaming website?  That's crazy talk.

Hmm the last time doctor told me to cut down on gaming because it's bad for my eyes i read 3  books (500 pages each) over the weekend :D

But seriously it's not that bad go to cinema, watch some movies, read books, spend some more time with missus (try to prend you are doing it especially for her and not because doctor told you so:D ).

Win win situation.

And if i'm reading it correctly you can still use your right hand for gaming as long as you don't doo anything with left hand ? Maybe it's time for some nice turn based strategy on pc (civilisation IV is cheap on steam and runs on almost any computer)

I thought about recommending reading books, but holding a paperback in your hands for extended periods can fatigue your thumb also. 

I have tendinites in my right hand, a condition that was created or, at least augmented, by gaming. This is one of the main reasons I almost exclusively play in the Wii.

First of all, you should reduce drastically the number of hours you use the controller. I say you should embrace motion controls and avoid the classic controller any game that relies too much in button pressing. There a lot of interesting hardcore experiences to the Wii remote and I guess it will be similar with Move. Also, if you're optimist, you can hope that Microsoft will eventually create something interesting to Kinect.
