AIBU to question a lactational atrophy diagnosis that is not improving?

[ZippyBlueViper]

10 months pp, breastfeeding and periods haven't returned, im 34. Since dd was 4 weeks been having awful vaginal symptoms. Burning, stinging, itching, hurts to wee, sex is a no go, constantly feels like I've got damp underwear. It's affecting my mood massively because i feel uncomfortable and disgusting most days. I'll randomly get the odd couple of days where i feel like i have a normal vagina but 99% of the time awful.
Been to gp and they said low oestrogen it's lactational atrophy and prescribed oestrogen cream to use once a fortnight.
Went back and they upped to weekly.
Went back upped to daily.
Went back said it is what it is and will take time.
Went back asked for a different gp for second opinion. They said same it's lactational atrophy.
I queried with both doctors could it be lichen sclerosus. Both have said no.
My question is if it is lactational atrophy why isn't it getting better with the oestrogen cream?
Can anyone who has suffered with either lactational atrophy or lichen sclerosus explain what it was like for them?
Aibu in thinking the doctor has got this diagnosis wrong?

OP can you afford to see a Gynae privately ? I would do that in your case if I could afford it.

Gp me yesterday said it might be folliculitus but she's not sure. Prescribed me antibiotics as well as the e string oestrogen ring. I can't really afford private. I asked gp again yesterday for a referral to gynecologist and she said not until I've had the e string for 3 months

Are you sure you don’t have thread worms? Has anyone else had them? They make the area really sore and inflamed. When did you last take a tablet?

Have you tried a barrier cream? General irritation is aggravated by the natural behaviour of the area.
I remember feeling miserable for ages, piles and general irritation. It all cleared up eventually but it was definitely quite hard to clear. Like a vicious circle, as each thing was treated the other thing started up.
