If you're into prevention, get an ergo-aware keyboard and mouse if you feel any discomfort at all.

The starting points - and for many people, perfection - are a split keyboard (like https://kinesis-ergo.com/shop/freestyle2-for-pc-us/), ideally with the center elevated ("tented"), and a vertical mouse (like https://evoluent.com/products/vm4r/). They have almost no learning curve. Kinesis has a 60-day money-back guarantee.

These products should leave your wrists and hands at the same angles as when they hang at your side. Let your arms dangle freely, bend your elbows, and type/mouse.
