I've only had my ears pierced, but my friend who has had his ears pierced and a couple of tattoo's on his upper arms, says having his ears pierced hurt more than having his tattoo's done. Obviously the pain from the tattoo's goes on over a much longer period than the sharp pinch and hot feeling that you get for a few seconds when having your ear or ears pierced. Another factor would also be the part of the body you are having inked as to how much pain is experienced.
