Today at work, I was doing nothing in particular when all of a sudden I developed a sharp pain in my right pinky finger
. When I looked at it, the area around
the vein closest to the top (the vein closest to the nail) had turned bright blue on the right side. A co-worker suggested I flex my finger to return circulation, so I did. After a while, the blue became a deep purple/light gray color. It also looks a little swollen and it's painful to touch. Any ideas as to what happened?
