vulva lump

I have found a small lump "down there" above where you pee from. It is under the skin and smaller than the size of a pee. It has appeared in the last 48hrs and today become quite painful. there is no visible marking on the skin, it does not appear wart-like more like a cyst? any idea what it is/what to do?

if this is painful i would get it checked by a phys. i have had similar cyst like eruption but i found this was caused by friction!but it was never painful.i would watch this area to see if  it changes in size or becomes even more painful.

even if it's not painful, you should have it checked by your doc just to be sure
