I have had the same issue for about 2 months now... Small, irritating spots on my labia, and a yeast like vaginal itch. I am almost 40, and know how to care for my "stuff" regarding baths, undies, feminine products, diet, etc, as they all affect how we feel down there.I have been tested for EVERYTHING, and nothing! All negative. We are doing a biopsy this week for better results, just in case.
I was, however, on antibiotics for dental surgery, and all symptoms went away! Used them for a week, and bumps came back about 4 days after antibiotics were gone. WHY??? I mentioned it to my gyno, but not sure if he was really listening... What could cause this irritation?
