What are the symptoms of allergic urticaria

Allergic urticaria is a manifestation of urticaria, which usually appears on the calf within 24 hours after onset. However, the repeated occurrence of new rashes has a great impact on people's normal life. So what are the symptoms of allergic urticaria? Many people don't fully understand this. In fact, there are four symptoms of allergic urticaria, and the most common symptom is systemic symptoms.

First, the most common is that patients have systemic symptoms. Such as chills, fever, sweating, dizziness, nausea, headache, joint pain, fatigue, difficulty breathing, etc. Moreover, symptoms of allergic urticaria tend to occur in pressure-prone areas of the body, such as the palms, soles, buttocks, and upper back, and rarely on the face.

Second, skin lesions are common. The lesions are large erythematous plaques with deep edema and central vascular compression that appears white. Lesions rarely extend beyond the site of compression.

3. Edema is found deep in the skin. If the skin is squeezed between the thumb and index finger, it may take on an orange peel appearance, indicating edema deeper in the skin.

Fourth, the appearance of wheals usually occurs locally 4-8 hours after the skin of patients with allergic urticaria is compressed. The duration of skin lesions is 8-72 hours, with an average of about 20 hours.

In addition to the above common symptoms of skin diseases such as allergic urticaria, a large proportion of allergic urticaria patients often experience itching, stinging, and burning sensations.

The above-mentioned manifestations are common symptoms of allergic urticaria. If similar symptoms appear in our body in life, we must go to the hospital for regular examination and treatment in time. We must not take medicine privately because of so-called experience. Not only will it not be effective, but it will cause more trouble.
