Sinister.
I think that my right hand is suffering from excess computer use. This is no joke. I've had a bruised feeling in one of the fingers of my right hand for some time now. I also notice a feeling of strain in my right forearm. I mentioned this at the Victoria yesterday and got a variety of responses. Jim (Celtic Tiger) Britton said that I was probably not taking my hand off the mouse while I used the PC. I think that he's right. Others told me that I was getting Carpel Tunnel Syndrome.

One chap even explained his theory that it was caused by Optical Mice. This rings true for me, as I noticed things getting worse after I got an optical mouse. His theory is that users move their hands differently with an optical mouse, in a way that causes more strain on the wrists.

Midway through my afternoon at the Vic, I held my right arm in the air with the elbow high and the hand hanging down to show everyone that my little finger was shaking uncontrollably. Luckily it didn't last long.

So I am experimenting with using the mouse with my left hand now. I've changed the mouse settings so that the index finger does most of the work. Apart from the odd bit of typing, like this, I'm letting the right hand do nothing.

I will let you know how it goes.
