HI, thanks for using healthcare magic
It is possible that it is a bartholin cyst
. The bartholin glands are located on each side of the vaginal opening. Sometimes the glands become obstructed resulting in swelling of the gland.
The fluid in the cyst can sometimes become infected.
It is possible that it is recurring because the cyst itself needs to be removed.
You may want to consider visiting your doctor for an evaluation.
I hope this helps
