Hi Thank you for asking HCM. I have gone through your query. Your problem can be due to decreased moisturization or fungal infection. Avoid soaps and irritants to wash the area and instead you can use saline or warm water. If you were my patient then I would suggest to use ointments containing anti fungal agents like miconazole, anti bacterial like gentamycin and corticosteroid like beclamethasone for local application. You can also use creams based on liquid paraffin for moisturization. Hope this may help you. Let me know if anything not clear. Thanks.
