My boyfriend and I had sex and the next day my vagina hurt, I took some advil and relaxed that entire day. The next day I woke up to ONE of my vagina lips inflamed. It hurts and I can barely sit, or walk. [ which sucks because that's all I do at work ] I keep taking advil to try and help the pain. I can't afford to go to the gyn. What should I do? Is it just irritated? How long does it take to go away?
