I have had a microdermal piercing on my face for over a year. Nothing has ever happened to it, it has never become infected or anything of that nature. About a week ago, a small lump began to form around the piercing which has slightly increased. It is filled with pus. A piercer said it was a bubble and can go with sea salt water, another said it may be keloid and will go with steroid cream. The piercing is stil in as I don't want to fondle with anything and I haven't yet had the chance to see the doctor. What do you think this could be? Is it something to worry about?
