What causes bumps in female private area?  

Visual DX. Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
Could be anything... From razor burn to warts or herpes. It's best to have it evaluated in person or via virtual consult. Hope this helps!
