Hello, Thank you for posting on HCM. It seems you are suffering from Tinea cruris/corporis, a kind of fungal infection. I would suggest you to consult your dermatologist for proper management of the condition. I usually recommend proper course of oral anti-fungal drugs like Fluconazole or Itraconazole along with anti-fungal cream like luliconazole for local application at bedtime. You can additionally use antifungal dusting powder containing sertaconazole during day time and a soap containing ketoconazole for rinsing of affected areas. Take oral antihistaminics for itching as required. Maintain hygiene over those areas and avoid wearing tight undergarments. Hope this will take care of your problem. Wish you best of health. Thank you Dr Hardik Pitroda
