Within the last six months I've developed arthritis in both my hands (and ankles). Each morning when I wake up both of my hands are stiff like they've been in ice water.

My right index finger which I use for scrolling using my mouse scroll wheel (and typing). when I bend in in the morning my index finger it will make a snapping noise. None of my other fingers make the snapping noise.

The odd thing is it isn't the joint. If I bend my fingers in the morning and my index finger snaps you'd think it was the joint. I experimented and cracked my index knuckle after it made the snap and the knuckle snapped.

Anyway that's a tale of my bizarre life somewhat related to this topic.

I find scroll wheels dangerous on the index finger, as it gets quite a workout. I prefer touchpads/ mousepads for scrolling, but I'm curious if foot pedals would be better.

Interesting—I scroll with my middle finger, always have. I thought everyone did. Makes sense in retrospect that different people would find different "intuitive" ways of using a mouse, though!

I do now!
