Didn't have true carpal. Had ganglion cysts at the base of my thumb. 3x removing them made scar tissue. Had to clean that out because I lost all feeling in my fingertips and couldn't hold a glass in my right hand. DeQuervains 2x in the thumb tendon, then my elbow got involved. They removed bone to create more room for the ulnar nerve, I grew it back. Removed it again, I grew it back. Finally they did a transposition. Now the nerve that jangles when you hit your "funny bone" goes inside my arm under the muscle and goes back outside at the wrist. No more funny bone!
I've had splints & casts on my right arm so much I'm basically ambidextrous with the mouse and the number pad (bought a USB number pad to use with my left hand...).
That's another part of why I'm retiring. I'm tired of all that too.
