question: My wife has got white marks on the back. On seeing doctor, doctor diagonised as skin fungus. He advised to apply Ketovate Solution ( Ketoconazole solution) one hour before taking bath. In night , Kansel - ds lotion to be applied. This treatment is going on for last 2 months but there is no improvement. We have observed that it starts in summer and continues for 2 months. This gets cured within 2 months. But, this time it is not getting cured. Please suggest what to do as my wife is very much worried.
