I've basically been suffering from an itchy anus for the last 5 years, and in the last year it's spread over my scrotum as well. I've been prescribed 'Fucidin H' but it says in the leaflet not to use it on the anus and genitals! Any advice would be greatly appreciated because this itch is driving me mad! White, flaking stuff seems to come off whenever i scratch around the perineum and there is some scaling on my scrotum now. Please help!
