Hi, During hot humid conditions one can get fungal infection, frictional intertrigo or heat rash in groin. Ebernet will only work for fungal infection. In intertrigo, mild steroid will be required and if it is a heat rash calamine lotion would soothe the area. To relieve itching, one can take cetirizine However as a general measure keeping the area dry, clean and ventilated, wearing loose cotton underclothes and using an antifungal dusting powder would keep all problems at bay. Hope that answers your query. Take care.
