Thanks everyone for your advice and suggestions.
I managed to get into the dr tonight as it had gotten worse.
Turns out its a type of dermatitis and its spread to around the top of the vagina. (Sorry TMI )
EXTREMELY painful cause it started to raise and blister but hopefully the antibiotic cream will clear it up soon.

I don't even know how things like this start but OMG i feel for people that have any type of dermatitis all the time now!
