What causes skin to scratch?

Skin marks upon scratching may be artificial urticaria, which is one of the types of urticaria and has a tendency to heal on its own. Artificial urticaria is the most common type of physical urticaria, which is mainly manifested by skin scratching, scratching, and pressure may appear as linear elevations surrounded by a red halo, which may be accompanied by itching symptoms. The etiology of the disease is not clear, and may be due to the release of vasoactive mediators from mast cells after mechanical stimulation of the skin. Usually, artificial urticaria can disappear on its own after a period of time and does not require special treatment. For those accompanied by intense itching, antihistamines such as loratadine and desloratadine can be used. There are other reasons why the skin gets marks when you scratch it, so it is recommended to consult a doctor in time to clarify the cause of the disease and actively treat it.
