You should just leave it alone and see your provider about it as soon as you can to find out what is going on.

Now that i wrote that last night, i looked this morning and instead of being a consistent pink color it looks like one side of it is lighter in color, almost white as if there's fluid inside. It almost looks like a big pimple, but I'm almost positive it's not, as it's been there for weeks.
It's also the only one of its kind. I've never seen a cluster of bumps together. Hope this helps
Herpes wouldn't go unchanged for a month in the genital area. It's something else going on down yonder.
