You cannot safely get rid of a nose piercing bump overnight
Leave the piercing alone and do not twist or pick at it
Clean the area gently with sterile saline
Use a warm saline compress for 5 to 10 minutes
Avoid alcohol, hydrogen peroxide, tea tree oil, and harsh ointments
Do not remove the jewelry unless a professional tells you to
Reduce irritation from makeup, masks, glasses, and sleeping on that side
Make sure the jewelry is the correct size and material
See a professional piercer if the bump is growing, painful, or not improving
See a doctor if there is pus, severe redness, fever, or spreading swelling
