Dear madam, what your husband seems to have is most likely a fungal infection and right now there is also some bacterial infection which has mixed with it because of the itching battery does over the area. Before starting the treatment I need to know if he has any more patches between the thighs, around the waist or on the buttocks. Since when does he have this condition? does anybody else at home have it? You can send me the pictures online with the answers to the questions and do an online consult for more information. Hope this was helpful. Take care.
