If your dry, itchy skin does not get better within two weeks, see a doctor. In some cases, dry skin and itching can be due to an allergic reaction or a skin disorder such as eczema or psoriasis, which may require specific treatments. Severe itching can sometimes be a sign of a more serious condition, including liver disease and cancer.
Scratching can cause your skin to become infected. Signs of infection include redness, tenderness, swelling, and pus. Call your doctor if you have any of these symptoms. You may need antibiotics.
