Uh... Hello!

I'm 13 years old, and this is a very personal problem, and I'd like to refrain from telling my guardians.

I'm not sure how long it has been there, but there is a small, about the size of a pea, lump on the wall of my "area", and I'm really scared. It hurts when I put a finger over it, and pressure would hurt it more. I discovered it while typing and I went to stand up, and I felt a pain in there!

I really have no idea what to do, and I'm not sure who to go to for help, but should I be scared...? Please answer!
