Is this a vulva cyst or does it look like an std? just noticed within the past few days but ive had the same partner fkr 7 yrs

I’m not sure with regards to other types of cyst but it’s not a bartholins.

I get them in the same area. Doc said its not a BC because of the location, but they treat it the same. I’m constantly on antibiotics and now I’m trying Phoebe’s Cure. Very painful for me.
