Hi, last wednesday i realized that my genital area was a bit itchy. When i put a mirror up to it i realized that my right labia minora was swollen and the source of the itch. Due to me itching before i looked down there, the area was red, had an odor worse than usual and a few bumps had formed, like a rash. I took it as nothing and began to put anti-itch creams, vaseline, and even lemon on the area as i thought it might have been a yeast infection. At the time the rash had began it was about a week before my period was due. Since then it has spread to the upper region of my right thigh and part of my left labia minora. Could this be dermatitis, a yeast infection, or some kind of std? Please help :(
