Urticaria is a relatively common rash in our daily lives, which can occur at any age. The etiology of urticaria is very complex, including many aspects, which also have genetic factors. Therefore, it is still necessary for us to understand the common symptoms of urticaria, which will help us to make corresponding countermeasures to make the disease heal earlier.
Clinically, the common symptoms of urticaria are as follows:
1, ordinary urticaria: Ordinary urticaria patients will initially complain of itching, and as the itching increases, the patient’s skin will appear windy. The color of the wind group is red or pale, its size and shape are different, and the onset time is uncertain. As the wind masses gradually spread into pieces, the patient's skin and hair follicles will dent downward. It is especially important to note that the duration of the wind mass on the patient's skin varies from a few minutes to a few days. After the patient's skin subsides, no traces will be left. During this period, patients may also experience symptoms such as nausea, vomiting, headache, bloating, abdominal pain, and diarrhea. In severe cases, they may also have chest tightness, pale complexion, accelerated heart rate, weak pulse, decreased blood pressure, shortness of breath and other systemic symptoms.
2, artificial urticaria: patients with artificial urticaria may be too sensitive to external mechanical stimuli and cause related physiological reactions. Therefore, the patient's skin will produce wind lumps. In addition, if the patient scratches the skin because of itching, artificial urticaria will form on the skin.
3. Solar urticaria: After the skin of patients with solar urticaria is exposed to the sun, the local skin will quickly appear itching, erythema and wind masses. When the patient develops a rash, it may be accompanied by symptoms such as chills, fatigue, syncope, and intestinal cramps. These symptoms will disappear within a few hours, so don't worry too much.
4. Contact urticaria: patients with contact urticaria have allergic reactions due to skin contact with related allergens, causing wind masses and erythema. The incidence of non-immune contact urticaria is relatively high. As long as the contact is in contact, the disease can occur, and no substance sensitization is required.
5, cholinergic urticaria: patients with cholinergic urticaria will have generalized small wind masses on the skin other than the palms and soles, especially the surrounding skin in these places. Most patients occur during exercise or shortly after exercise. Patients will complain of itching, tingling, burning, heat or skin irritation.
