Last week, I experienced some itching, but it was very mild and white discharge. My sister said it was a yeast infection and offered to buy me a kit but I declined because the symptoms were so mild and basically went away. This morning (about a week later), my vagina lips have been itching sooooo badly and when i looked in the mirror, they were kind of red and swollen and looked like I have some kind of a rash. Also, where my vagina meets my inner thigh are these tiny little bumps and it's red in the crease. It kind of itches from time to time, but not really. Should I have taken my sister up on her offer??
