Hello, Welcome to HCM, The history and symptoms suggests me that you are having a fungal infection but it should be confirmed by physical examination. Don t be embarrassed to show and confirm the diagnosis. The fungus are the normal commensals of this area which will be kept under control by the helpful organisms, whenever there is a change in environment because of multiple reason these fungus will multiply and produces the symptoms. I would suggest you to follow 1.Keep the area dry and clean by maintaining the good hygiene. 2.Topical antifungal cream should be applied. 3.Tab Diflucan, 150 mg single dose will help to control the symptoms. 4.For itching you can take anti histamines. Thank you.
