Skin | Dermatology | Itchy Skin (Symptom)
Itchy skin is an uncomfortable, irritating sensation that can make scratching irresistible. Sometimes itchiness lasts a long time and can be intense. As you rub or scratch the area, it gets itchier. And the more it itches, the more you scratch. Breaking this itch-scratch cycle can be challenging.
Itchy skin can have hundreds of possible causes. Also known as pruritus, itchy skin may be the result of a rash or another condition, such as psoriasis or dermatitis. Itchy skin may be a symptom of an internal disease, such as liver disease or kidney failure. Though itchy, your skin may appear normal.
Itchy skin may occur in small areas, such as on an arm or leg. Sometimes the whole body may feel itchy. Itchy skin can occur without any other noticeable changes on the skin. It may be associated with: redness, bumps, spots or blisters, bry, cracked skin, leathery or scaly texture to the skin
Diagnosis and Treatment
Identifying and treating the underlying cause of itchy skin is important for long-term relief. Itchy skin treatments include medications, wet dressings and light therapy. Self-care measures, including anti-itch products and cool baths, can also help.
