I pierced my nose 3 months back and it had healed completely and it was normal. But I had knocked my piercing a few times over the past month by accident and 2 weeks back I developed a bump near my nose piercing. Please refer the image attached. Should I remove my piercing or leave it on and let it heal on it's own? What should I do for the bump to heal quickly and what can I use to treat the bump? Please advice as soon as possible. Thank you.
