Little Bumps...

Hello!

So i woke up to find loads of little bumps under the skin around my Vagina Lips area. I have never had this before, they are under the skin and causing a little pain but nothing too bad. I have been with my partner for 3 years and we have both been checked before. he isn't cheating (incase that was a thought) I have a doctors app today, just want some advice?
