The internet is crazy full of resources for carpal tunnel relief. I just kept trying stuff until i found what worked.
My problem was a ton of tension/tightness in my forearm muscles that was leading to inflammation in the wrist making using mouse/keyboard pretty unbearable, even for browsing the internet. If you do some basic forearm/wrist stretching while probing the muscles for pain/tight feeling you will be able to tell if something is wrong.
I fixed it by doing a combination of stretching, rubbing really hard on the muscles, and pushing into the muscle while activating it. I would finish by holding my wrists in ice water. The whole routine took 10-15 minutes and after doing it for a weekish I was playing FPS games pain free.
