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.
