My veins stick out, but not all the time. The worst thing is that they are really visible, but they can't use them to draw blood. I'm like a pin cushion when they need to put in an IV or take blood.
Sometimes, veins become visible all over my body, like a map: bright blue veins all over. Very spooky... Then they disappear again.
