It is very common to have acne on the body. There are many reasons for it. Getting angry, allergies, urticaria, etc. can all cause this symptom. If the symptoms are not serious, you can ignore them and observe them yourself. Pay more attention to rest, develop good living habits, try to eat light food, do not eat spicy and irritating food, and eat more fresh fruits and vegetables. What causes urticaria? Seasonal urticaria, urticaria is called "red and white wandering wind" or "rubella" in traditional Chinese medicine. The occurrence of this disease will have a great impact on people's normal work and life. Urticaria, commonly known as hives, is a localized edema reaction caused by dilation of small blood vessels and increased permeability in the skin and mucous membranes. The clinical manifestations are wheals of varying sizes that occur suddenly, disappear quickly, are extremely itchy, and leave no traces after healing. Things you need to pay attention to with seasonal urticaria are: try not to scratch. Scratching will not only fail to relieve the itching, but the itching may become worse. This is mainly because when you scratch the area, it will increase the local temperature and cause the blood to release more histamine (allergens), which will make the condition worse. What are the symptoms of urticaria? 1. When seasonal urticaria occurs, wheals and red spots appear on the skin, with tingling, burning pain, fever, and recurring symptoms accompanied by severe itching, which worsens before going to bed or when getting up in the morning. Urticaria occurs quickly and gradually subsides within a few hours, leaving no trace after subsiding, but it can recur, even multiple times a day. 2. In most cases, a clear cause can be found. The disease usually occurs suddenly, often with itching first, and soon reddish or pale wheals of varying sizes appear. They are oval, round or irregular in shape, and the number is uncertain. They may be localized or widespread throughout the body. The size and shape of the wheals vary and may merge into large pieces. 3. Seasonal urticaria symptoms often disappear naturally within one or two hours or several hours, or at most within 1 to 2 days, but new lesions often appear elsewhere. Generally, no new lesions will occur within 24 hours where the seasonal urticaria symptoms have disappeared. After the symptoms disappear, the skin returns to normal, sometimes with temporary pigmented spots called pigmented urticaria. The size and number of seasonal urticaria symptoms vary and can appear on any part of the skin or mucous membranes. |
