I have a 12 year old daughter who has had vaginal itching for some 18 months now and it is driving her (and me) crazy. we have had every lotion and potion, skin alergy tests, blood tests etc etc etc. I have changed washing powder, new underwear, washes with pure products or nothing at all. in this time she has started her periods but the itching continues. she is extremely embarrassed and now doesnt want to go to school. please help i dont know what to try next?
