I'm searching for a diagnosis of skin condition that I have since childhood. The symptoms include extreme itching on skin with white/cloudy scaling, followed by darkening of the affected area. After scratching the area and removing scales, the skin burns. The symptoms start showing at random on skin. So far I've had the condition on legs (behind knees), arms (elbow joint) scalp (rear head), partially on lip and pelvis area. The legs, arms and lips areas do not have itching and scaling anymore, yet the dark skin is still there. I'm still suffering from the symptoms on the rest of the affected areas.
