bumps

For the past few months Ive had this bump in the middle of my lip. It's a raised bump, but when you look closely it is actually made up of small bumps. There is one bump in the center with the other bumps around it. It kinda is in the shape of a flower. It doesnt itch and I dont even know it's there unless I look in the mirror or feel it when I close or lick my lips. It's bothering me and I cant get into the dermatologist for another 2 1/2 weeks. I also had the gardisil shot about 2 years ago. Do you have any idea what this could be? It's starting to worry me.
