I too got a yeast infection and broke out into red itchy bumps on the lower left side of my labia. I also had a canker like sore on the inside of my vagina next to my urthera along with cakey white vaginal discharge, itchiness all over and it burned to urinate. I was perscribed Diflucan( 3 day dose) which got rid of the burning urination, the canker like sore and the discharge. Now 1 week later my vulva itches and the bumps are still going strong. I have been using Tea Tree Oil directly on bumps and that seems to be helping them mend. Here's a little info, as far as STD's are concerned.. if your partner ever had cold sores in their mouth, by performing oral sex on you, they can spread Herpes to your genitals.. This is called HSVI.. The scary part about it is it hides (dormant) in your nervous system along your spine and does not always show symptoms.When your immune system takes a hit (menstraul or a cold) it will show its' ugle face. Herpes (HSVI/HSVII) is life long and will continue off and on. Get tested just to be sure, as I am getting tested tomorrow. Good luck!
