Hi, Thanks for yhe query I undrstand your concern. The rashes you describes are likely to be fungal infection(follows excessive sweating,lack of hygiene)or allergic(alleegy to talking powder,barhing soap or fabric used for the garments) Home management consists of finding possible cause. Steroid based skin ointment application & removing cause of sllergy helps allergic rash Frequent bathing,wearing cotton loose garnments,application of antifungal ointment most of the time help fungal dermatitis. Fungal dermatitis aggravated with steroids. If no relief with suitable ointment/condition aggravates.. consult dermatologist for suitable oral medication. Thanks.
