Well, it depends on everyone. Some places hurt (such as the shin bone, chest, ect.) and some places, not at all ( near the outside of the elbow) but it all depends on the person. Some spots hurt and some don't.
It does hurt, but how bad it hurts all depends on your pain tolerance. For some people it feels like a lil sting and for others it seems like you cant take it anymore. Defiantly get one but if it hurts to much tell the guy giving you the tat, he should be able to help you out.
