<s>[INST] From last 2 or 3 months I had a white spot under my scrotum sac and it itches may be once a day more or less in night or in morning .. but I think its size increased in past few days not sure .. when I use some anti itching cream itching goes, request you to help me out on this [/INST] helloThanks for the query.Probably you have developed  a fungal infection.The area of scrotum is bit moist and is prone to develop fungal infection.It can be easily treated with the use of an antifungal cream.You can use an over-the-counter anti fungal cream like clotrimazole.Remember to use the cream for at least one month continuously.Maintain good personal hygiene.it's better to meet a dermatologist and get yourself examined.Let me know if you have any other doubts.Thank you. </s>
