Hi,

After reading your query it appears to be due to Fungal infection of the area which is quite common due to heat and humidity. Fungal infection of the skin is quite common due to infection and hygiene as well as most commonly due to diabetes.

If I were your dermatologist then would have prescribed clotrimazole cream or terbinafine cream over the affected areas under medical supervision. I suggest you to take antifungal tablet by mouth such as fluconazole 150 mg alternate days for 15 days.

If itching is present then you can additionally take antihistamine benadryl or loratadine by mouth.

To prevent the further spread maintain good hygiene wash it two times properly. Stay away from hot and humid climate.

Take care.
