Basically, I masterbated with a blanket.  The next day or so I started having pain near my clitoris and my labia near it.  I figured it was just a friction burn and it would go away soon, as I've had them before. It started to get worse, and a lapse of judgement made me try to put baby powder on it to help the pain and I had it on for maybe 30 mins.  

The next day, and this has lasted about a week so far, I've developed big greenish blisters on my labia near my clitoris, and it's even spread to look like I have one within my vagina.  I've also developed little blister-like bumps on the bottom of my vaginal opening, and big ones next to my anus that are itchy and painful.  These wake me up at night.  I'm currently out of state so seeing a doctor is hard.   I have no history of STD's and I've been with the same partner for 5 years, My discharge, while a little thicker, seems normal and doesn't smell bad.  It stings bad to urinate.  

Is there anything I can do for this?
