I'm 17, 18 in a few months, a Junior in high school, and even though i've been waiting months for it to go away I itch. I have had yeast infections before, the itchiness, swelling, discharge, but I took some over the counter pill for yeast infection and my vagina still inches, swells and It's turning whiteish with small bumps on one side. Also even though i've been taking my vitamins, and eating everyday; if I don't eat for a hour or so I start getting lightheaded and sleepy and have a hard time staying upright. I've passed out once but that was a year or two ago, I've fainted recently but I don't know. Do I have a infection and diabetes or something? Should I see a doctor?
