I am 18 years old, female, and in generally good health. I have good hygiene. I just recently noticed that on the rim of my anus a lump had formed. It's a little bit larger than a pea, skin toned, and if inside of it there is a smaller more firm piece. It doesn't hurt..isn't uncomfortable. Occasionally it becomes itchy. I researched hemmorhoids and warts, it does not sound like either..
