Medically termed pruritus, itchy skin can arise as the result of several different skin conditions. Marked by an excessive itching of the skin and frequently an unusual rash or texture to the skin, itchy skin is often uncomfortable and can even be embarrassing. As dry itchy skin can develop due to several factors, identifying the underlying cause of the issue is crucial discern an appropriate treatment.
Itchy skin may develop on a single part of the body, such as the arm or leg, or over the entire body. While dry itchy skin can occur without any additional noticeable symptoms, it is often associated with characteristic changes of the skin. Common symptoms of itchy skin include redness, bumps, blisters, spots, lesions, dry and cracking skin and a leather or scaly texture to the skin. The duration and intensity of itchy skin varies by case, but it often lasts a long period of time and is intense. Additionally, rubbing or scratching the area typically intensifies the condition or at least the itch, so it is important to not scratch the dry itchy skin.
Itchy skin is most often caused by dry skin or xerosis; however, xerosis is not the only cause of itchy skin. Additional causes of itchy skin include skin conditions or rashes include eczema and psoriasis, internal disease such as liver disease and celiac disease, nerve disorders, irritation and allergic reactions, drugs and pregnancy.
