How do I pop a bartholian cyst, it hurts I have a painful vaginal cyst about the size of a grape on rt mid - lower inner vulva

Avoid sharp objects! I recommend applying warm compresses to the area for 10-15 minutes, several times a day. A bartholin's gland cyst or abscess is a little deep for 'popping' and you may make it worse. If it doesn't drain spontaneously, your ob/gyn can do an incision & drainage in the office, and/or (esp if it comes back) a procedure called a marsupialization to prevent recurrences.
