The symptoms of itching skin include bruises, skin redness and dry skin with cracks, according to Mayo Clinic. The itching may either be general or localized; however, itchiness on the skin may not cause noticeable signs.
Itching skin is a skin condition in which a person feels irritation and an urge to scratch, explains Mayo Clinic. The skin's appearance may be normal, rough, bumpy or full of blisters, depending on the cause. The causes may include dry skin due to environmental factors, excessive washing of the skin, and internal diseases, such as kidney failure, iron deficiency anemia, liver disease and thyroid disorders. Nerve disorders, such as diabetes mellitus and sclerosis, may also cause itchy skin.
