Moms of daughters I need your help!!!!

Has any one else had a daughter here that was born with a thin flap of skin covering the vaginal canal? My daughter is 9 (the same age I was when I first got my mensies) and she's complaining of lower middle stomach pains. I don't know if this could be related to that or one other issue she has, but I want to know how you got this issue fixed or when it fixed itself? I'm worried and don't know what to do at the moment for her to help.
