Bumps on my vaginal area, after my laser hair removal.

I had a laser hair removal done recently, it is my 3rd session, but since that last session I've noticed that I had some bumps that won't go away. They are not the red itchy bumps and neither do they have pus on them. They do not hurt or itch. It's like a permanent bump that grew after my laser. Can anyone tell me what it is? Can I freeze it off?
