Hi,
Thanks for the query.
According to your description that could be bartholin cyst.
Bartholin gland will be located near the vaginal opening.
When the duct get s blocked it will form cyst.
Infected cyst will form
abscess. It can recur.
So you once consult gynecologist get examined and take treatment accordingly.
