This is because closely apposing body folds e.g. thighs and groin, maxilla, submammary folds etc. can trap sweat, heat and moisture, therefore making the area favorable for fungal proliferation. If I was the treating doctor I would have asked you to use a topical antifungal like clotrimazoleketoconazolefluconazole cream, twice daily, regularly for 4 weeks. An Oral antifungal e.g. fluconazole once weekly for4 -6 weeks OR oral terminating once daily for 2-4 weeks OR Itraconazole 100 mg capsule, 2 capsules once daily for a week, is also advisable for a more complete urban OTC antihistamine e.g. cetirizine 10 mg once daily would help you in symptomatic itch relief. Keeping the folds Chat Doctor. Regards
