What are the symptoms of scabies?

The main symptoms of scabies include the following aspects: 1. Severe itching: After scabies mites bite the skin, they cause intense itching, particularly severe at night, often affecting sleep quality. Itching commonly occurs in areas such as the finger webs, wrists, elbow pits, armpits, waist, and genital regions. 2. Skin lesions: The skin may develop pinpoint-sized papules, papulovesicles, or small blisters, often numerous and scattered. Long-standing scabies infestation may lead to rough, thickened skin and lichenification. 3. Linear burrows: The tunnels excavated by scabies mites beneath the skin are one of the reliable diagnostic signs of infestation. These burrows are typically shallow, fine, and winding, reaching lengths of several millimeters to over ten millimeters. 4. Scabies nodules: If scabies infestation occurs on the scrotum, penis, or labia, it may result in pale red nodules the size of soybeans. These nodules generally do not resolve spontaneously and are accompanied by severe itching. If the above symptoms appear, it is recommended to seek medical attention promptly for professional diagnosis and treatment.
