Hello,
This persistent
vaginal itching can be caused by various factors and
uncontrolled diabetes is one of the most common cause for it.However there can be various other causes like...
Skin infections like yeast or STD's
Skin conditions like eczema,psoriasis etc
Low estrogen levels in menopause or breast feeding
General disorder like thyroid disorders.
Sensitisation of vulval skin to soaps,sanitary wears,condoms,detergents,deodorants,fabric conditioner etc.
Since you are already under the treatment of your gynecologist,so carry on the treatment but do get an opinion from a
dermatologist for conditions like eczema or psoriasis or
lichen planus etc.
Along with the treatment offered,do the following also...
Control your diabetes meticulously.
Wash your vulva gently every day and dry it completely before putting on underwear.
Underwear should be loose and 100% cotton
Avoid wearing any underwear in night.
Avoid soaps,detergents etc
Avoid shaving pubic hair
Avoid fabric detergents
Use non perfumed toilet tissue paper and sanitary towels
Use petroleum jelly locally.
Avoid condoms lubricated with
spermicide.
I hope it helps
Thanks
