Hello and welcome to healthcaremagic You seem to have fungal infection of the groin folds. Body folds, specially when they are deep and closely apposed to each other, as in people who are overweight, presents an ideal environment for the fungus to grow (warm, moist and humid) specially in summers and in coastal and tropical areas where body sweats a lot. Clinically it presents with itching skin which is sore, red and scaly. Treatment is commonly based on: -Antifungal creams: Either Clotrimazole/Ketoconazole/Sertaconazole/ OR Luliconazole for 4-6 weeks -Antifungal tablets: Either Fluconazole/Itraconazole for 4-6 weeks -An oral antihistamines like either Cetrizine/Fexofenadine or Loratadine can be taken once or twice daily symptomatically, for the itch associated with fungal infection Some general measures like: Wearing loose fitting clothes, cotton undergarments, bathing twice daily(in summers), managing one s weight (if overweight) and sticking to the treatment for the entire duration (4-6 weeks) goes a long way in getting the desired results. regards
