Rashed on Scrotum. Pic for your perusal.

Hi Doc, I am having rashes on scrotum from last 3 days. Earlier I thought may be because of sitting for entire day at one place, moisture because of sweat would be the reason so I used talcom powder to keep the area dry and clean. But then the I started having itching when I took a notice it showed strange pattern on skin of red rashes. Again since it was mild I started using soframycin cream and salt water bath to treat myself. I also tried heat therapy (warming a cloth and placing it on scrotum in case of immense itching sensation only). But this all seems to be a temporary solution as after few hours it start itching again and in the morning it's uncontrollable and the urge make me do it. Now it is the 3rd day of using cream and I was thinking to use pure turmeric paste (turmeric powder and water) as well. But just want to know if there is something serious I should pay attention to that I might be taking as lightly. Hence, please help, I have attached a pic for your perusal.
