Although it would have been wise to biopsy
when it did appear and treat you for herpes
(if that was the cause), when the wart did appear there is no point commenting on it right now.
The description provided now does not resemble that of a wart or herpes for that matter. It instead resembles that of a simple cyst
or a Bartholin
cyst. You my look this up for better understanding.
Antibiotics along with warm baths and warm compresses applied several times a day should help if the suspected diagnosis is right. But if you do not experience an improvement, visiting a doctor would be the best next step.
Hope this helps.
