I pierced my nose 3 months back and I had no infection and it had healed completely. 2 weeks back I developed this bump near my piercing. It is not because of any allergy or infection from the piercing because it was completely healed and normal for 2 months. But I knocked my piercing few times since and it hurt a little. I want to know if I should remove my nose piercing or can I leave it on and let it heal on its own? What can I do/use for the bump to heal quickly? Please advice. Thanks.
