Itchy skin can be a result of a number of things. According to the Mayo Clinic, itchy skin can be caused by anything from a rash or dermatitis to a sunburn and even liver disease. If the itching is severe, always talk to your doctor if it persists for more than a few days or if you experience additional symptoms.

Rashes can occur on their own, or as a symptom of a more serious or widespread condition. Itchy rashes can take longer to heal due to the compulsion to scratch. Remedies are available to help ease itchiness as the rash heals, though some treatments that help control the itchiness will not help heal the rash.
