Most nose piercings are safe as long as you keep the nose piercing clean and free of bacteria.
If the nose piercing gets bacteria in it and becomes infected then it could make you sick.
It's a good idea to use some apple cider vinegar or rubbing alcohol to keep the nose piercing clean and free of bacteria and to prevent infection.
Don't change out the nose piercing too soon either otherwise it could cause the nose piercing to become infected or close up.
Always keep the nose clean and the area around the nose piercing clean and you should have no issues with getting sick from the nose piercing.
