What does Hill urticaria symptom have

summary

I don't know why my skin is very bad. I'm always allergic and prone to wind. Recently, my skin is itchy. I can't help scratching it. I feel better after applying ointment, but it itches again soon. Everyone says it's urticaria. Today, let me talk about the symptoms of urticaria.

What does Hill urticaria symptom have

Symptom 1: papular urticaria is mainly caused by the allergic reaction caused by the bite of mosquitoes, bedbugs, fleas, lice, mites and midges. The reason of the disease is that insects pierce into the skin and suck blood through their mouthparts, and their saliva and some mouthparts remain in the skin. The disease often occurs in infants and children, especially in summer and autumn.

Symptom 2: the typical skin lesions are mung bean or slightly large reddish papules, hard in nature, with small blisters on the top, scabby after scratching, and spindle red halo around them. After scratching, they appear as wheezes, and they still return to their original shape after the wheezes subside.

Symptom 3: the course of the disease is different. It usually subsides spontaneously in about one week, leaving temporary pigmentation. However, new rashes can appear one after another, so new and old lesions exist at the same time. When the weather turns cold, it gradually recovers, but it often occurs the next year.

matters needing attention

Papular urticaria mostly occurs without protective measures. For those who have a history of papular urticaria or allergic constitution, oral antihistamines can be used before entering the environment with possible pathogenic factors, which can avoid the onset or relieve symptoms.
