you could have THRUSH, when i had thrush it itched very bad and my skin went very red and my lips down their swelled up bad and it wasnt very nice but i got some cream then it was alright. i used to get thrush from fragranced SOAP.
I once had this and the itching and burning was so bad that I hardly payed attention to the frequent feeling that I needed to urinate, until I went to the Dr. and they discovered that I had a urinary tract infection. Why all the itching, I'm not sure, but that's what *I* had, at any rate.
Feel better soon!
