Spine
Tattooing over the spine can cause a burning sensation in delicate areas of bone, skin, and nerves. The needle touches nerves along the spinal cord, sending signals to the brain. Spine tattoos are intricate and may take longer to apply, so beginners should consult an experienced artist.
Back
Back Tattoos are among the most painful (9-10). With no padding from muscles or fat, there is less cushioning from pain. Back Tattoos tend to hurt more than other designs.
Top of the Foot
The feet and ankles have many sensitive nerve endings and little fat or muscle padding. This makes them an extremely painful tattoo spot. When getting a foot tattoo, wearing comfortable footwear and using shear-reducing products like Saniderm is best. Small foot Tattoos may help alleviate some discomfort.
Ankles
Tattoos on the feet and ankles are notoriously painful (9-10). Little fat tissue insulates the thin skin in these areas, and the bones close to the surface can feel like someone is poking directly into them.
Knee and Knee Ditch
The knee and knee ditch can be susceptible (9-10). A major nerve, the sciatic nerve, runs down the leg. The area also has tight skin from constant flexion, making healing more challenging, especially for people prone to friction.
Chest, Rib Cage, and Nipples
Tattoos on the chest, rib cage, and nipples rank highly for pain (9-10). These areas have minimal muscle or fat cushioning due to their bony nature. They also take longer to heal properly and are more prone to infection due to exposure to elements.
Hands and Fingers
Tattooing hands and fingers is considered one of the most uncomfortable tattoo locations. These areas are bony, with thin layers of skin containing minimal fat or muscle. Tattoo ink doesn’t adhere well in this area.
Remember that pain tolerance can vary from person to person, but areas with high nerve densities and minimal fat or muscle are likely to be more uncomfortable for tattooing.
