Hi. Thanks for your query. Noted your history of recovery from yeast infection of butt and now have itchiness of the scrotum with white patches on the sides and there is more itching in the night. The history is suggestive of dermatitis and most probably with secondary infection with yeast. I would advise you the following: Clean the area with plain water three time a day, make the area dry with hair dryer. Apply liquid povidone iodine and let it also dry . Once the area is clean it will show the clear diagnosis and further treatment with antihistamine, oral steroids and anti-fungal tablets surely help you to get a relief. Avoid hot and humid atmosphere, dampness is the basic cause of all such problems. Use loose clothes.
