Hello, I have a cluster of small bumps on the labia. It occurs when I am a week or so from the start of my cycle. It doesn't appear every month or it sometimes appear right at the end of my cycle. It doesn't hurt however it itches from time to time. I have been tested for Genital Herpes and my resutls came back NEGATIVE. What can I do to prevent this from occuring and what can I treat it with when it does occur? I am 39 years old. I am 158 lbs and I stand 5'5. I do have HBP.
