Shoulders: These are one of the most common tattoo spots, and for good reason: they're equally easy to show off and cover up. Luckily, they can also be pretty basic in terms of discomfort, healing, and wear. The closer to your shoulder blades and the larger the design (if it extends up your neck, for example), the more painful the tattoo can be.
Spine: If even the slightest thing sends chills up your spine, this may be a spot to think twice about. Your spine is not only notoriously sensitive, but extremely bony and filled with nerves — all of which are a recipe for pain.
