Mine is also on the inside of my wrist. It says Diabetic . My artist was concerned if I needed help and someone looked at my wrist, they might think it was just art. He added a red caduceus within a red block star thing and a shield underneath. I have quite a bit of time in ER over the last 4 years and I can honestly say, the only thing they look at is the word.
If it says too much or is too small, EMTs are working as fast as they can. They only have time to glance.
