The treatment for fungal infection is simple. You have to take anti fungal tablets and creams for few weeks following which it resolves. Do not apply soap on that area and do not self treat with over the counter steroid creams. Mistreatment with steroid creams and self treatment with cheaper medicine is the most common reason for recurrent disease. intraconazole should have worked but cheaper brands often result in treatment failure.
