Itchy vulva. It starts itching after my period especially during ovulation and stops again when my period starts. The itching is intense, when I scratch I get cuts on my clitoris and labia and they bleed. My labias and clitoris itch and sometimes around the anus. When I scratch my vulva and get cuts and bruises they hurt very much and it becomes uncomfortable walking. The itching and pain is very unbearable.This has been going on for more than 6 months
