A nose piercing is a body piercing that requires special care because of its susceptibility to germs and the nose's proximity to the brain. The nose and brain share the same blood supply. If your nose piercing becomes infected and is not cared for properly, the infection could spread to your brain.
See your doctor if your nose piercing becomes infected. Do not remove the nose ring jewelry - if the hole begins to close and the bacteria become trapped, the infection could spread through your system.
