Urticarial Rash, which is also known as hives, is a rash that is a result of fluid leakage from blood vessels just under the surface of the skin. The rash is generally very itchy and may appear suddenly, lasting for about six weeks. Apart from the itchiness another symptom of hives is swelling of the eye, lips or around the genital area. This swelling occurs because of a condition called angioedema. It occurs when the fluid released by the blood vessel seeps into deeper layers of tissue, causing inflammation. Generally hives requires no specific treatment. Often a cool shower or calamine lotion helps relieve the itchiness, antihistamine tablets are also helpful for curbing the symptoms.
