A few weeks ago, I started to get a pins and needles sensation in my wrist. It began right at the base of my thumb and continued down.
I naturally ignored it.
Over the course of several days, the tingling spread up through my index finger and down towards my elbow. It remained centered on my wrist and seemed worse in the mornings.
With the morbid half-panic of someone just weeks away from her fortieth birthday, I decided that I was having a heart-attack, or a stroke, or something equally horrific.
I finally had it checked out; and the diagnosis was one which would have had my old work colleague shrieking, "I told you so!"
Carpal Tunnel Syndrome is basically wear and tear on the innards of your wrist. You'll need to check with someone more medically qualified than myself for the fine detail. It's caused by repeatedly performing the same action over and over again.
Like typing, or moving a mouse, or anything else that us gamer, geek, freelance writing types do all day, every day. Contributory negligence then.
So how did the Kensington Trackball mouse prevent this, if a doctor said that I have it? My carpal tunnel is only in one wrist. The left side is screaming out for relief. The right side is sitting pretty on the mouse and hasn't given me so much as a twinge.
