The most painful places to get a tattoo include the armpits, the ribcage, the genitals and the face. The knees, elbows, feet, neck, and hands are also considered painful spots for tattoo placement.
As a general rule, areas with thin skin over large veins or areas with bones close to the skin are considered the most painful locations to tattoo. These areas tend to contain a high concentration of nerve endings close to the surface. Spots with a protective layer of fat, such as the thighs, buttocks or upper arms, are considered the least painful to tattoo because the fat acts as a cushion between the tattoo needle and the nerve.
