Itching skin can indicate mild to severe conditions and can also occur in some serious, even life-threatening conditions, such as severe allergic reactions that include anaphylaxis and allergic purpura. Itching can result from infection, inflammation, allergy or sensitivity, insect bites, and other abnormal conditions.
Depending on the cause, itchy skin can be short-term and disappear quickly, such as when itching occurs due to a buildup of dead skin cells. For example, if you feel itchy all over and live in a dry climate, you may have “winter itch,” which is caused by the lack of moisture in your skin.
Itching can also occur in sudden episodes, such as itching that happens when a person is exposed to an allergen that causes a rash. Itching can also occur over a relatively long period of time, such as when itching is due to chronic eczema.
Itching can occur by itself or in conjunction with other symptoms, including rash, runny nose, and sneezing. In addition, excessive scratching can introduce bacteria or fungus into the layers of the skin, resulting in infections. Tell your health care provider about any symptoms that occur with itchy skin. This information may help your health care provider diagnose the condition.
Itching skin accompanied by difficulty breathing and swelling of the tongue or face may be due to an allergic reaction and anaphylaxis, which is a life-threatening emergency that should be immediately evaluated in an emergency setting. Seek immediate medical care (call 911) if you, or someone you are with, have any of these symptoms. Seek prompt medical care if you do not have symptoms of anaphylaxis, but the itching is persistent or causes you concern.
