Three days ago, I noticed a lump on my right labia majora. I though at first that it was an ingrown hair or something, but since then it has spread to a bigger, sore, painful bump and become quite red and kind of stiff. There seems to be a small amount of some sort of white discharge, but I haven't noticed any strange smells.
Almost a week ago now, I began taking penicillin, prescribed to me for my strep throat. I'm hoping this problem has something to do with the antibiotics (which have a LOT of possible side effects). Any ideas?
