The people I used to work with usually mainly got direct pain & sx in the wrist area with carpal tunnel. They wore the splint and recovered for the most part.
I never got CTS , but did have some wrist & joint pain due to the strained muscles up my arm and into my neck & shoulders causing a tension & pulling effect all down my arm. My dx back then was bi lateral chronic wrist strain,and some shoulder strains per GP & a physiatrist.
But I did not majorly recover until my upper body tightness was resolved.
The sx were mostly showing in my hands & arms but it was farther up the chain that needed the treatment for approx 85 % recovery. I'd say I'm now at a mild but chronic stage mostly myofascial sx now & mild vascular if arms are held up for more than 2 minutes or so.
But yes double crush & even triple crush as they are called can happen.
That would be TOS plus CTS and or Ulnar/cubital tunnel.
Have you tried any self care & posture, relaxation things or have a friend help with looking for trigger points -
