I'm quite lucky, actually. I have such a low tolerance for pain that if it gets real intense - I pass out! Can't feel it if you are unconscious! Now, that said I have had a 1.5 and 2 hour tattoo and a nipple piercing this year and none of them hurt very much. The artist warned me when she headed toward my underarm (just a half inch or so), but it was no worse. There was one place on the outside of my shoulder that felt like she was digging for bone, but it was just a brief unpleasantness. I'm planning one for my forearm from wrist to elbow that may take up to four hours and I don't plan to take anything. Might take Advil after to keep swelling down if it seems a problem. I know I'm a real wimp when it comes to pain, just so far haven't hit a sensitive spot. When you do, please keep me from hitting my head on the floor. Thanks!
