Hi, Devki ji,
Welcome to HCM,
From your history it seems that you have got chronic fungal infection
You may require oral anti-fungal medicine for complete cure.
Take tablet Flucanozole 150 mg once in a week for 4 weeks.
Apply local anti-fungal cream.
keep local part clean, dry, airy and healthy.
For itching you may take Cetrizine
as and when required.
ok and bye.
