Can septum piercings cause breathing problems?

Yes. Material may build up on the piercing, the septum may become infected and enlarge, and the piercing itself may limit the airway. I don't recommend the practice. Talk to your doc for more insight. Hope this helps!
Septal piercing. Septal piercing is a bad idea. There is increased risk of infection and nasal obstruction is not unheard of. Have your nose evaluated by a board certified otolaryngologist,
