Since February I’ve been experiencing an itch on the vulva close to urethra I’ve been to the doctors twice they prescribed antibiotics but it hasn’t work I’ve had a fungal cream which hasn’t helped so I had an investigation with a mirror and next to my urethra is a hole bigger than the pee hole and it is extremely itchy sore tender, I had cin 3 cells on cervix 2 years ago and treatment for endometriosis at the end of march. What is it why has a hole appeared freaking out. 
any replies thank you x
