I have the same problem..I had sex with my boyfriend and a few days later i had this rash up by my vagina in my inner thighs... I was really nervous cause i thought it was an Std but my boyfriend doesnt have anything like that so i looked it up and i see that it either might be a yeast infection or just some rash...i do have bad dry skin so when it gets really cold or dry out my legs break out with rash's so im thinking thats it because theres nothing on vagina its just down by my ass on the outside my vagina doesnt hurt i mean at first it was a little sore but not anymore.. and im not discharging anything its just really ichty i keep scratching which ends up burning so i stop i dont know i think i might be over reacting a little i believe its just a rash theres no bumps.. it doesnt smell. just really itchy when i dont scratch it kinda goes away.. so i should probably stop.
You should go to the doctor immediately to check it out. They can test for STDs and also other things like staph (MRSA) infections to give antibiotics if needed. They also have creams that could help with the irritation and pain. Hope you feel better after that!
I'm in the same boat but the itching is all over the front of me; from nape of neck and scalp and down to the labia,
under the breasts. Think I'll try the natural way by taking warm and not hot showers/tubs; not staying in them
long; and drying off quickly and then put a moisturizer on to keep the cells moist. And, drink several glasses
of water a day. Winter Itch gets worse as we age and genetics play a part too, especially if w're of British/
Scottish/Irish roots. That would include Scandinavian, Russian, etc. heritage too I'd imagine.
