Blister on clitoris

Help, I have a white painful blister on my clitoris, i have had it looked at but the doctor told me it was just from friction. It does reoccur after sex, so i am concerned it is something worst.

it is white and located at the connection to my clitoris.

has the blister gone away or does it come back after phyiscal touch ? i know with mine after sex it gets very sensitive to the touch . what does it look like now ?

I think you should use protection when having sex. Using condoms may lower the pain.
