Surgery for my one year old?????

So I changed my daughters doctor and when we went she checked her vagina. ( Bare with me cause I wasn’t understanding what she said ) and she never specifically told me a name for it ... so I don’t know exactly what part on the vagina but she said that it was too in? And that if it doesn’t fix itself with a rash cream she gave me then she’s going to need surgery to open it up. I’m definitely going to get a second opinion about it but I was so confused. Has anyone heard about this?
