I have a white patch of skin about the size of a dime in my pubic area that has been there for years. If I squeeze on it or dig a fingernail into it, the itch is absolutely unbearable ! ! I can scratch until it bleeds and it will then itch EVEN MORE ! ! I hope this is not serious. I was with a promiscuous girl many many years ago. If anyone can help me, I would appreciate it. Thanks !
