Let us understand the facts on Urticaria here. Urticaria is a medical condition that is also called as the nettle-rash or hives in a layman’s language. It simply means itching on your skin with rashes all over. Broadly defined, urticaria is also known as the skin eruption that is either allergic or non-allergic from its very origin. It is a condition that is characterized by intense itching and red circular or very irregularly sized eruptions on almost any part of your body.
Uriticaria appears on the skin and is an allergic or non-allergic immunological skin disease. Generally it is a condition that raises above skin level, coupled with acute itching and a slight warmth. This again could be either acute or chronic and has a tendency to recur for months or years. Such eruptions remain on the skin for a considerable period, for seconds or even hours. The eruptions can disappear and reappear and often disappear without leaving any trace on your skin.
Location:
Urticaria can appear on just almost any part of your skin. Some of the patients have eruptions once in a while, and some could have eruptions many times during the day. While some have only a couple of spots on their skins, others do have widespread rashes throughout their skins that may appear for days or even many months together.
Angioedema is another condition, wherein deep tissues are influenced. Urticaria comes with acute, chronic and recurring variants in terms of frequency and duration. If you observe under a microscope, an urticarial rash may exhibit a pervascular, cellular infiltrate that consists of lymphocytes and eosinophils that indicates the allergic behaviour of the skin. You can also see the swelling or oedema as well as mucosal inflammation.
What happens inside your body:
Urticaria is a condition that is characteristic of allergy and is an immunological event happening at the dermis. Due to the release of histamine, urticaria produces a hypersensitive reaction. This release of histamine could take place from the mast cells at the time when antigens and antibodies come together in order to activate the immunological reaction. Thus urticaria signals antigen and antibody reaction. In the process of this antibody-antigen reaction, the histamine or acetyl is generated. This has a tendency to cause vessel dilatation itching, swelling, and rash and pain.
It is very important to understand the basic facts on urticaria before you undertake any treatment. Urticaria, put in simple words is itching coupled with rashes all over the body. These rashes are characterized by skin eruptions that are raised above the skin level. This itching gives intense warmth in the affected area.
