In Case This Could Help Anyone!!
As the title suggests, this post isn't for everyone and every case has it's own circumstances. I got carpal tunnel about two years ago and it was pretty fast onset. It wasn't surprising, given I worked from home at the time and also play RuneScape (online MMORPG that's pretty time intensive, that primarily uses the mouse with a lot of accurate clicking and mouse movements with fast reaction times).
It didn't get much worse than after the initial onset but it was severe enough to continue to bother me. I bought a wrist brace and wore while sleeping and all the time at the computer, but even then after enough time my fingers would get that tingly numb pain feeling and stiffen up in all the expected ways.
I got annoyed enough that I started researching solutions, but one that caught my eye recently was that mouse wrist rests exacerbated the problem by putting pressure on the wrist and doing nothing to help your arms angle...
Arms angle...
Crap
I connected the dots and turns out the rapid onset was exactly correlated with getting my new desk. My desk is next to my girlfriends, and my old crappy IKEA desk was sagging and on the way out and I knew it was the same height as my girlfriends desk. I take one look at the desk I got two years ago to replace it, a nicer real wood desk I got lucky enough to pick from someone looking to throw it out, and...
The desk was a single inch taller.
I tried adjusting my chair, but my chair was at it's max height. Started researching the chair itself and if there was any way to squeeze out legit just one extra inch so I could lower my armrest compared to the seat and have a proper relaxed right angle arm.
Turns out, all it took was going from the default 2" wheels the chair came from to 3" wheels. I had no idea it would work and I doubted it would when I put them on, but since then I haven't had a flareup and that was a few weeks ago now.
TLDR, if you use your computer a lot and either work from home or play high intensity video games, don't neglect the proper balance between your height, your chairs height, the desk's height, and how it all relates to your arms posture.
