I have a chronic skin condition in the form of a rash composed of small, itchy bumps in isolated areas of my back, chest, arms and legs. The affected areas are not widespread but they sustain an endless cycle of itching and scratching. The diagnosis is "lichen simplex" which is also called, "neurodermatitis". The symptoms of lichen simplex (and related skin conditions) are well documented; but the cause of such conditions remains unknown. Intermittent symptomatic relief may be possible but there is presently no known cure. As I understand it, this condition could persist for months or years. Advice and comments based on the personal experience of readers presently or previously afflicted would be most helpful.
