I recently discovered a small lump right next to or on the opening of my anus. It is a little painful--not to the extent where its aching or I can't sit, but if I somehow touch it slightly it hurts. I took a mirror to look at it, and its a little purpleish, not too big (it feels bigger than it looks). Ontop of that, my vagina's been really itchy every since it appeared (4 days ago), but not my anus. And I have been constipated (which i never am). Its not an STD, I've never been active.
Help? Is it a hemmorhoid-or something else? My vagina has also been alittle purplish color..
