Dd has severely itchy vagina

[Bubbagirl]

My dd is now 4 and for about the last year she has been so itchy in her nounou (as she calls it). It's basically inside the outer labia and on the inner bits not actually inside her vagina.
We have been to the doctor 3 times and they've been totally unhelpful. We've ruled out worms and thrush and one of them said it was soap irritation and one said eczema. But no-one can give us anything to treat it.
She is itching so bad she makes it bleed. The skin is all stretched and saggy and she cries her eyes out with how itchy it is.
I feel so bad for her. She wears mits at night due to her eczema anyway but she still manages to scratch it really bad.
She doesn't use soap only an eczema special wash. We wash her hair in the shower so rinse it all off so I'm not sure it's soap irritation.
We put sudocrem and vasoline on it but it doesn't really help.
Anyone experienced this with their dd? Any tips on how to treat? We are thinking of asking for a private referral from our doctor but not sure if it's a dermatology problem or gynaecological??
Thanks in advance

@Bubbagirl
It is definitely a possibility- I hope she gets seen soon, poor little mite!

@bubbagirl,
How is your dd now

I know it's older Post my dd kind of facing same but not so much itching but dryness around vulva irritation

How's your dd

Hi @Rajalakshmi, she is much better now thank you. The specialist we saw diagnosed it as eczema still and gave us a much stronger steroid to use for a short burst to clear it up. It helped massively and within a week she wasn’t itching at all. She has had maybe 2 flare ups since then but they haven’t been anywhere near as bad and we’ve dealt with them with the milder steroid and moisturiser. She is also a bit older now so able to control herself from scratching quite so bad thankfully.
I hope your dd is better soon, it is so horrible for them. If you haven’t already ask your GP to refer you to a specialist as they will be able to diagnose and treat better. Xx
