How do I fix it?
1. Review your workplace ergonomic set up.
Proper positioning of your body at your work station is paramount to avoiding injuries such as this one, as well as sore necks and backs, sore shoulders, headaches, and more. If you spend 6+ hours a day using these muscles in a position that overloads them, it makes sense that they will develop an over-use type injury over time. So how do you fix it?
Focus specifically on your arm/wrist/hand position. Your upper arm should be in line with your torso, hanging straight at your side, with your elbow comfortably resting on the armrest of your chair. Next, you want to make sure that your forearms are parallel to the floor and your wrist is supported in a neutral position. This wrist support is very important; you don’t want to have to rely on the small muscles in your forearm to statically hold your wrist up all day (which can contribute to this injury!). Lastly, make sure that your mouse and keyboard are in reach of this position. Think of this upper body posture as your “home base”.
