Look carefully at a detailed diagram of the female anatomy. Is your lump in the vicinity of the
Bartholin gland? If so, call you PCP, tell them what you suspect and ask if you should schedule an appt in that office, or with an ob-gyn. I think women make much better ob-gyns, on the whole. Meanwhile, try soaking in Epsom salts, and try using a hot, then cold compress on the area. Use as hot as you can stand, but not hot enough to burn that delicate tissue.
