I recently have become very itchy down there my mom who does my laundry switched detergent and added fabric softner. I have since rewashed all my underwear but I still am very itchy and swollen. I do not have any std's or other issues.. I know it is due to the detergent and fabric softener.. When will it go away? Do I have to take anything? I was also wondering if I can still shave down there?
