Hi Thank you for asking HCM. I have gone through your query. Your problem can be most likely due to fungal infection and irritation. If you send a picture of it then it will be more helpful in identifying. Avoid using soaps and irritants to wash the area and instead you can use saline or warm water. In such case i would recommend creams or ointments with combination of anti fungal like miconazole , anti bacterial like neomycine and corticosteroid like beclamethasone for local application. Hope this may help you. Let me know if anything not clear. Thanks.
