Vaginal adhesion

LO had her check up the other day and DOC. Said she’s got vagina adhesion. To apply estrogen cream over it. I’m not sure if it’s right because the cream is supposed to be for labia adhesion and I’m not sure I want to break a hymen or something. I used a little bit today, and later on she was extremely red all over. I’m now using coconut oil to sooth the burn. Any advice or tips what to do?
