Weird cyst type thing in my vaginal area?

It's a boil...Apply Hot compresses to it, and Neosporin. You can also try hot baths...it's going to take awhile, at least a week...hope you are not in too much pain. Mine grew to the size of a golfball. Very painful.

Possibly a boil. Some ways to tell:

You can sort of move it around under the skin a little (i.e. not like a pimple)

It feels a little like a pea, under the skin

The area of skin on top of it may be darkish and sensitive to the touch

It hurts to squeeze the lump

There may or may not be a yellowish head to it (this would probably be later on)

Before i address your question, i have just an onservation for another answerer- CHRIST chemoangel! A GOLF BALL??

In other news, if you have to ask about a cysty-type thing in your delicate areas, you should definitely get to the MD I. The next few weeks. Schedule an appointment, and if you notice it growing in size, get in immediately.
