Help! What can this be????

[omgitchiness]

I have multiple menopause and vaginal atrophy symptoms.
I am on a cocktail of HRT.
When I went to bed last night and the itchiness was at another level!
It felt like a mix of popping candy, some sort of spider and small electric shocks in and around my vagina, vulva and anus!
It eased after an hour or so.
I've been fine all day until the last 20 minutes and it has started again!
What on earth can it be? Any idea how to ease it??
Thanks

Worms if you have younger kids?

I thought that too, but no young kids. I've been scared to google symptoms of worms but will do now.

Lichen sclerosis?

@sprigatito I'm not sure what that is but will google it. Thanks
