I saw what appeared to be a blackhead in my vaginal area (I get these from time to time). I was trying to remove it and it bled no blackhead came out. I kept trying for a while though. Once I stopped I realized it was swollen and kind of looked like a knot. The next morning it looked like a blister, not really hard, circular with a big white head on top. Did I just irritate and and is it a blister or something else? What would the proper care be for this particular area?
