Urticaria, commonly known as hives, is a skin disease that causes sudden blistering, reddening and itching of the skin.

Although it is usually the result of drug or food allergies, it has been shown that stress, autoimmune diseases and some viral infections can also cause urticaria.

The symptoms of urticaria are red, slightly raised, patchy rashes that may be one or several centimeters in size.

These rashes can appear in some areas of the body or spread throughout the body.

The causes of urticaria in children can be foods such as peanuts, shellfish, eggs, some medicines and other allergens.

In addition to these, studies have shown that urticaria that occurs in cold weather conditions, sunlight-induced, post-exercise urticaria also exists.
