Mommy help?

Mommy help ? Yesterday there was an irritation under the diaper of my little girl, she's very worried and cries when she has a bowel movement or pee. I applied zinc ointment, Bepanthen (by the way, after it got worse), I just rubbed olive oil on it. I bathed her in herbs, she is awake naked without diapers, changed the diaper for a Hagis. Well, I did everything I knew, but they haven't gone for two days (( What would you recommend? Maybe I'm doing something wrong?
