A clinical examination is very important before advising any treatment. A painful lump in the vulvar region, fever, swelling in that local area are few common presenting symptoms of this abscess. Take analgesic like Tynelol for pain relief. To help healing, soak the area in a shallow, warm bath or a sitz bath. The cyst may break open on its own but if it is very painful it may need to be drained. An antibiotic course may be necessary. Visit a doctor for assistance. Keep me posted.
Best wishes and take care!
