Hi, My son is having blisters that break along with itching around the buttocks area since the month of May. First set of blisters were in a small area which subsided by applying Neosporin powder. Next set came up in new spots increasing the infected area. All along itching also persists. Now since 3-4 days I am applying Candid ointment assuming it is a fungal infection. Though the existing ones are subsiding with ointment application, newer blisters are appearing in new places. Now it is spread toalmost half of the buttocks area(both sides). Kindly suggest an appropriate treatment. A picture of the infected area is attached for reference. Regards, Anitha
