Need help

Okay so I had my baby a week ago and I did not tear/ require stitches or anything I was good to go. However I do have this cut on the inside of my vagina lips, like on the side of everything there is a cut and it burns so bad when I pee bc I guess the urine runs over it. What can I do to help heal this? I don't know what Is okay to put inside my vagina over the cut.. Neosporin?
