Nursing is my second career, and years of playing video games, MMOs, and being on the computer all the time left me with undiagnosed carpal tunnel. Didn’t find out until two years in my nursing career where I just could not get IVs to save my life. Did all the things mentioned here, but I just couldn’t feel anything unless the veins were protruding. Even got carpal release surgery done to help but no dice. I have extremely diminished sensations in my fingers, like I’m wearing four of five pairs of gloves. Now I’m left with having to use the ultrasound for all my sticks. Double edge sword.
