You seem to have developing a recurrent fungal infection
, which can be either tinea
infection or candidiasis
You should try to keep the region clean and dry .
Do not apply any kind of oils or moisturizing creams over the region .
Wear cotton clothes inorder to reduce sweating.
You need to use an antifungal agent like Clotrimazole gel over the affected area twice a day.
Also you need to take oral antifungals .
And to relieve the itching, take oral antihistamines .
Hope it helps,
