The upper half of my left thumb on the inside (not around the nail) suddenly turned blue. what is this?

Vein rupture : Did you hit your thumb or bump it, right before? Sometimes people can have a small venous malformation from birth. You will need to find a phlebologist who knows how to scan with ultrasound. Have your primary care refer after exam. www.phlebology.org.
