Dry, hard and dark skin on the elbow is considered more likely to have neurodermatitis. It is mainly caused by mental tension, stress, poor rest and sleep, or repeated rubbing of the elbow. The rash can be characterized by hard patches with clear boundaries, deepened furrows, elevated ridges, fine scales, and a mossy rash. Treatment requires the application of a strong glucocorticoid ointment fluticasone propionate ointment applied once a day, together with dimethylsilicone oil ointment, to moisturize and nourish the effect. Usually this disease is also accompanied by a certain amount of itching, which can be treated with oral chlorpheniramine maleate tablets three times a day, one tablet at a time, or oral olopatadine hydrochloride.
