The main symptoms of chronic urticaria are recurring wheals and itching on the skin, which usually last for more than six weeks. If you experience similar symptoms, it is recommended that you seek medical attention promptly for a proper diagnosis.

The specific symptoms can be divided into the following categories:

1. Skin manifestations: Red or skin-colored wheals of varying sizes appear on localized areas or the whole body. They are irregular in shape and often accompanied by significant itching. The rash usually subsides on its own within 24 hours, but may reappear in new locations.
2. Characteristics of the attack: Symptoms may occur daily or every few days, last for a long time, and are easily triggered or aggravated by changes in environment, emotional fluctuations, or exposure to certain substances.
3. Accompanying sensations: Some patients may experience burning or tingling sensations on the skin, and a few may experience fatigue or sleep disturbances during an attack.
In daily life, it is recommended to record the time of onset, duration, and any related diet and activities, as this helps doctors assess the condition. Avoid frequent scratching of the skin, and wear loose-fitting cotton clothing to reduce irritation. Please follow your doctor's instructions for standardized treatment; do not self-medicate. Regular follow-up appointments will help better control symptoms.
