Hello
Thanks for writing to us.

Typical yeast infection has the " cottage cheese " white patches.
However, labial yeast infection CAN present as peeling, soreness and drying out of skin.
Antibiotics do wipe out normal flora of the genital tract, and can predispose to yeast infection.
Continue taking the Diflucan, and also use Nystatin or other local antifungal creams to provide relief.

One small possibility is some peeling skin disorder, but that should be considered if you do not respond to the antifungals and the peeling persists, and the skin diseases can be differentiated from yeast by your doctor after examination and appropriate testing.

Rarely, mycoplasma pneumonia could cause activation of latent herpes infection, and that too can be picked up on your check up.

Meanwhile, continue with Diflucan and add a local antifungal ointment too.

Meanwhile, some general pointers for vulval health :

Do not use fabric softener / harsh detergents for washing your undergarments. If you use a shared washer or dryer, such as a laundromat, you must hand wash and line dry your underwear, towels, and any other clothing that comes in contact with your vulva. .
Wear allergen free cotton underwear, not nylon or lycra etc.
Do not keep the area wet and moist for long.
Do not use bath soaps, lotions, gels, etc, which contain perfumes.
Do not use soap directly on the vulvar skin. Use warm water and mild lather, and gently XXXXXXX dry.
Do not scrub / XXXXXXX dry vigorously / douche your private parts.
Use white, unscented, simple toilet paper.
Avoid use of tampons for the time being, unless bleeding is quite heavy. Use sanitary pads with a cotton liner.
Avoid using hair removal products till the inflammation subsides. You might want to trim the vulval hair.
Avoid Lubricated/latex condoms, contraceptive jellies, creams, or sponges which may cause itching and burning.
Get your blood sugars tested, and maintain an active lifestyle with a nutritious diet.

Take care and feel free to ask for further clarifications.
