I have newly discovered a small circular, raised lump on my left labia majora, not painful. I noticed about 2-3 days ago. I assumed it was an ingrown hair, so I attempted to pop it. No fluid was inside of it, but since then the lymph nodes in my left groin have been swollen and painful. I still have no pain at the lump, but I am still very concerned. I have had no other symptoms, am monogamous, and a healthy woman otherwise.
