What are the symptoms of urticaria? Watch out for these 5 symptoms

Urticaria is divided into chronic urticaria, acute urticaria, artificial urticaria, etc. Urticaria is characterized by recurrent attacks, which brings infinite pain to patients. There are many detailed understandings of the symptoms of urticaria.

1. Chronic urticaria

The systemic symptoms are generally mild, but the wheals may occur more or less frequently and recur repeatedly, sometimes lasting for months or even years.

2. Acute urticaria

The onset is acute, with severe itching, and red wheals of varying sizes soon appear. This rash comes and goes quickly and can occur several times a day. Severe cases may be accompanied by symptoms such as palpitations, irritability, nausea, and vomiting.

3. Cholestatic urticaria

It is common in young people. It occurs when exercise, heat, etc. increase the temperature deep in the body, prompting acetylcholine to act on mast cells. The wheal appears within minutes after being stimulated, and may disappear within half an hour to an hour, with severe itching.

4. Artificial urticaria

Also known as skin scratching. After scratching the skin with your hands or scratching the skin with a blunt object, the skin will be raised along the scratches, accompanied by itching symptoms.

5. Solar urticaria

A few minutes after the skin is exposed to sunlight, itching, erythema and wheals quickly appear locally. The wheal disappears after about 1 to several hours. The rash may be accompanied by chills, fatigue, fainting, and intestinal cramps, which disappear within a few hours.

In addition to the five common types of urticaria mentioned above, there are also contact urticaria, exercise urticaria, tremor urticaria, aquagenic urticaria, adrenergic urticaria, electrical urticaria, etc., but these are very rare types of urticaria in daily life.
