Hello sir, I am suffering from red ashes, and skin tear in my groin since couple of years but sometimes it goes and then comes back, it burns and inches, I think this is due to my 12 to 16 hrs continuous sitting in the library and then when I come back to my hostel room at night 12, it itches and then fluids like pus comes out, the skin turns red and tears too, red and just like rough skin and then it gets dry .i think it is tenia cruris. What are the medicine can take?
