My skin on my butt cheeks started a sudden infection in 2020. It was red flaky and patches on the outside are raised and itchy. Nobody in my family has this skin problem and I've went to many clinics with many ointments and creams yet no result. It's mentally and physically hard for me to adjust into this irritation when I don't even know what is it . It starts itching the most at night and have slowly spread a lot .
