I cut my labia shaving!! HELP!

So when I shave, I get really in there and make sure I shave everything...I open my lips with my fingers and even use a smaller razor to get in there. Problem is, about 5 days ago, I cut my labia in 2 places and I didn't feel it then but after a day or 2, it's been really itchy. Can someone tell me if this has happened to you and what I should do? Let it heal or put some type of cream? I use vagisil wash everyday and have excellent hygiene.
