Thanks for writing to us.
Sometimes yeast infection does not respond alone to topical medicine. Oral antifungal
will be required. For the same you need to consult a dermatologist
again as its a prescription drug.
In the interim
Do warm water compresses of the lesion. Let it dry completely and then apply steroid antifungal antibacterial cream ( antifungal alone wont help as lesions are weepy) twice in a day. keep the area dry by wearing loose cotton underclothes and change the underclothes twice in a day. Also dust the area with antifungal powder to keep it dry. Do not use any soap detergent dettol or home remedies
as it can irritate the lesion more. If itching is unbearable take tablet cetirizine
twice in a day.
Hope that helped.
