Do you have a wrist rest? Is it for your keyboard or mouse? Is it made of gel or foam? Does it have grooves in it? Is it firm or soft? Is it black or purple? Maybe sparkly pink?
There are many things to consider when purchasing a wrist rest, but one thing is often overlooked: Do you know when and how to use it? As the name implies, wrist rests should be used only while resting. Here are a few other things to remember:
Wrist rests are not wrist supports.
When typing or mousing, your fingertips (or possibly your palm when mousing) should be the only part of you that is in contact with your equipment.
Give your wrists a break when you pause to think about what to type or when waiting for a screen to load.
Rather than bending at the wrists while typing or mousing, keep them in a straight (neutral) position over your keyboard and mouse.
