Oral and topical antifungals
Thank you for posting on HCM
From your description and history, it seems you have got extensive Tinea, a sort of fungal skin infection
I would recommend you consult a dermatologist
for proper management.
I would also recommend some laboratory tests especially to rule out diabetes and other immunodeficiency
I generally recommend proper course of oral antifungal
drug like fluconazole / itraconazole for 6-8 weeks along with local application of novel antifungal creams like sertaconazole
or luliconazole cream over affected areas. As the condition is fungal there is no role of any antibiotic or steroid cream,so kindly avoid other medications.
Use ketoconazole based soap and shampoo for daily rinsing of body areas.
Use antifungal dusting powder over private areas to keep them dry and free of fungus.
Take oral antihistaminics for itching as required.
Avoid tight fitting garments and maintain hygiene.
Avoid sharing of soap and towel.
Hope this will take care of your problem.
Let me know if you require any more help from my side.
