i have had this problem for a while and it called toilet disease. Ladies next time u wanna use the bathroom make sure it neat and clean and dnt sit on a public toilet seat because these stuff are transferable , make sure u clean urself and mind the soap u use with time it would go away.AND MAKE SURE U WEAR CLEAN PANTIES OR USE A PANTYLINER.
I have the same problem. it started about 7 days ago. i've had the same problem previously aswell though this time the only difference is that my vagina is not as swollen. i did go to the doctors previously and she said it was just a normal yeast infection. she gave me a over the counter cream and it worked.
but this time around, i havent been to the doctors however ive been treating it myself with vaseline and detol (disinfectant), it has been working so far and my condition has gotten a little better, but for faster improvement i might just have to go back to the doctor for prescribed medicine.
