I accidentally cut the inside of my nose. it did bleed for a few minutes. i am not sure how to clean to prevent any infection. what can i do?

Hello. Fortunately the nose has a very rich blood supply which means that as long as your immune system is normal, your nose should heal without any further treatment. If you have bacitracin at home or bactroban ointment, you could place a bit on a q-tip then place inside your nostril then give your nose a squeeze or a dab. You do t need to put it inside too far. Saline mist can help too.

As long as it is not bleeding, you do not need to do anything. The nasal mucosa will heal on its own. Wish you good health!
