The main symptoms of urticaria include:
Hives: Raised, well-defined lesions that may be red at the edges and pale in the middle are called hives.
Pruritus: is characterised by mild to extremely acute itching.
Evanescent Character: Although fresh welts may develop on different parts of the body, one of the most distinguishing features is that individual welts typically vanish without leaving a mark in less than 24 hours.
Angioedema, or swelling of the skin’s deeper layers, can occasionally accompany urticaria. Angioedema frequently affects the hands, feet, lips, eyelids, or genitalia and can result in pain or tightness. Angioedema that affects the tongue or throat is a medical emergency because it can make breathing difficult.
Types of Urticaria
The main way that urticaria is categorised is by how long it lasts:
Acute Urticaria: The most typical type is acute urticaria. The reason of outbreaks is frequently known, and they typically last less than six weeks.
Chronic Urticaria: When breakouts last longer than six weeks, chronic urticaria is diagnosed. Chronic spontaneous urticaria, also referred to as idiopathic urticaria, is a condition in which the reason is frequently unclear.
Additionally, there is physical urticaria, also known as inducible urticaria, where a particular external stimulation causes the hives to appear, like:
Dermographism: When the skin is scratched or rubbed, hives form.
Cold Urticaria: Cold exposure can cause cold urticaria.
Pressure Urticaria: Constant pressure on the skin, such as from tight clothing, can result in pressure urticaria.
Solar Urticaria: Sunlight exposure causes solar urticaria.
Cholinergic Urticaria: A rise in body temperature, as during exercise or a hot bath, is linked to cholinergic urticar
