Hi, My Name Is Sam. I Need Your Advice, I

Hi, my name is Sam. I need your advice, I have a lump a little ways above my clitoris, and it's painful when pressure is applied. At first, I thought it was just a cyst or pimple, but it doesn't pop or have any pus come out. The reason I'm asking you is because I'm 12, and I rather not tell my mom or see a gynecologist unless necessary. Any advice about it?
