I just wanted to mention that I used to have the "turns white" and now after much self care, chiro and PT, I instead get "prickly red" with bulging veins. My interpretation is that I had ATOS (not enough blood getting in) and now have VTOS (pinched veins traps the blood in the arm). I'm able to reduce my VTOS symptoms by 80% or more by shoving my first rib down.

The VTOS also seems easier to endure than the ATOS. Maybe that's because it's easier to fix and/or because with ATOS you are looking at a compression closer to the heart.

I'm continuing with the conservative approach, so don't have much to say about surgeons.
