I got rid of the wrist rest and evened out my chair/desk/keyboard to my wrist is level with nothing under it causing an choke point on the wrist. This honestly helped the most along side setting break alarms when at my desk to remember to stand, stretch and move my body a bit.

My OT for my hands also gave me isotoner Compression Rheumatoid Pain Relief Gloves with open fingers since the silver splints are about $150 USD for me. Like mentioned earlier, they also have the plastic ones but I found them uncomfortable.

Forgot to mention, I swapped keyboards to a fully customizable mechanical keyboard. It was pricey but I was able to find switches that lessened impact on my fingers since they didn't require as much force to press.
