What is urticaria?
Urticaria is hives which means rash on your body. It is reddish wheals or welt bumps that appear on your skin. Urticaria is also known as Nettle rash. This condition mainly consists of wheal spots or patched of raised red and white skin, each of which clears away in few hours to be replaced by fresh wheals. The welts may vary in size and fade repeatedly as the reaction course sets in. It sometimes occurs together with swelling of various parts of the body typically the face, hands, and feet called the angioedema. Angioedema is another skin condition and name given to the deeper swelling affecting the tongue mouth throat and upper airway.
Urticaria with angioedema may occur at a different time or together in the same person. It may occur in two forms. A wheel that is skin-colored or pale skin swelling usually surrounded by erythema or redness that lasts anything between a few minutes to twenty-four hours. It usually causes itching and burning pain in the skin. Angioedema is the deeper swelling within the skin and the mucous membranes. When hives last more than 6 weeks it is considered chronic. And when hives are without any cause it is considered idiopathic. Hives can be very uncomfortable interfering with sleep and normal day to day activities. Sufferers often don’t say anything at all they are too busy scratching which may lead to worsening of the situation.
What causes the rash?
Most of the time you cannot pinpoint the cause of the rash. Whatever is the cause your immune system senses as a hostile invader and kicks into overdrive mechanism. Tiny build vessels begin to leak protein-rich fluid and this causes a build-up of the fluid under the skin leading to red patches wheals and welts which results in excessive irritation of skin along with itching. The first line of defense is the skin.
There are two types of urticaria :
Acute urticaria: which lasts for the duration of up to less than six weeks
Chronic urticaria: which lasts for more than six weeks which episodic flare-up of wheals.
An outbreak that looks alarming the first thing in the morning can be gone by noon only to be back in full force later in the day. Because hives fluctuate so intensely and so fast it is helpful to bring along the photograph to a dermatologist for further evaluation. Hives appear when histamine and other compounds released from the cells called the mast cells which is found in the skin. Histamine causes the fluid to leak from the local blood vessel leading to swelling of the skin. Hives are very common but not contagious.
