Suggest Treatment For Severe Vaginal Itchiness In A Child

Hi: I have a 6 year old daughter that has been complaining of vaginal itching for 6 weeks now. She also says that it hurts down there like something is pushing This all began 6 weeks ago after she had a lot of sweets. I ve been to her pediatrician many times... NO UTI - they also put her on an oral yeast medicine for three days in case it was yeast related and it did not help We then went to a pediatric urologist... they thought that it could be constipation as young little girls can hold their pee and poo at school and then cause constipation and can cause these vaginal complaints they did a xray it showed normal they also did an ultrasound that showed normal They wanted her to try Miralax anyway so we have been on that for 3 weeks. we have seen very little improvement. I actually think she is NOW constipated ON miralax... and has a hard time going since we began miralax I also had her seen by a gynecologist who did do a swab and it all came back normal The urologist said to keep on Miralax and then the next step would be do a cystoscopy under general anesthia... I would prefer to not do that as it has some risks Have you ever heard of a young child that suddenly gets vaginal itching and then says something hurts feels likes it pushing --she points to the top of her clitorius area We do NO bubble baths - she never sits in soapy water ...I use ALL FREE and Clear laundry detergent and Aveeno soap to wash her...we never wash her with soap down there. I m really desperate for help and answers... The urologist has her on Miralax thinking its constipation..which the xray showed NO constipation and she NEVER had constipation before. Should we try and find a pediatric gynecologist group..? Any other ideas of what this could be? thank you very much
