This is from my left calf and the artwork is based on the original symbol for the medicine back in the greco-roman times. The snake is a western diamondback rattlesnake from growing in the desert of western Colorado. The whole thing is a because I have been a medic in the army for the last 7 years and I intend to be a RN when I exit the military. The ink was done by Dino of Tiki Tattoo in Lacey, Wa.
