First of all excuse my English its not my native language. Im live a remote area in west asia where hospitals are not close to me so I ask you to diagnose me with my skin problem. I suffer from these rash and acne coupled with blackheads, whiteheads, pimples, red/black spots and cysts. They center around the side back, elbow, upper arm and Buttocks. However my face is completley clean from this problem. I dont know if its related but I have seborrheic dermatitis since my childhood and i managed it well through medical shampoo. please help me i attached pictures
I am definitely not a doctor, and doctors do not provide medical advice to patients they've never seen in person before. I would not ask random internet strangers for a diagnosis! Only a doctor should do that. There is too much false information and too many uninformed people on the internet.
I see you have what appears to be severely dry skin. Have you tried treating that with moisturizing creams and seeing what effect it has on your skin? Dryness can irritate all kinds of skin conditions and make them worse.
