Can I Use Soframycin For Persistent Itching Over The Clitoris Despite Antifungal Treatment?

I have an itch over clitoris area. There was a fungal infection for which the gynac gave me a proper course of fluconazole both orally and vaginally. Infection is gone as checked by gynac but there is itching at the clitoris area. What to do now as have tried clocip, surfaz sn, candiderma+ but to no ise. Can I use soframycin over here as i feel that it might be bacterial now ?
