The amount of pain when getting a finger tattoo can be higher than other areas of the body because the skin is more sensitive, and there is less padding provided by muscle. The inside of the finger also may hurt far worse than other areas of the hand.
Getting a tattoo always involves some level of pain. The pain varies depending on the location of the tattoo and the pain threshold of the individual.
Any location on the body that has less muscle, including the feet and hands, experiences more pain since the bones and tendons are closer to the surface. This means that the vibrations from the tattoo machine resonate through these parts more intensely. Hand and finger tattoos are also more likely to lose ink during healing and are more prone to infection, since it is very difficult to limit their use.
