The ache is in your shoulder, and the cause is 30cm to your right
Most desk pain advice starts at the wrist, which is why most of it does not help. The movement that wears you out is the reach: shoulder out, elbow away from your body, arm unsupported in the air, then back again for the next line of the spreadsheet.
Do that for eight hours and the load lands on the trapezius and the muscles across the top of your back. Your wrist is fine. Your shoulder is doing the overtime.
