The living environment is unsanitary and there are many bags on me. What if it itches?

You may be talking about hives. It is localized edema caused by the expansion and exudation of small blood vessels in skin mucosa. This is a common allergic disease. If it is related to the environment, try to avoid contact with allergic factors, open doors and windows for ventilation, clean and sanitary, and change quilts, sheets and clothes frequently. For unknown reasons, anti-allergic drugs such as loratadine, chlorpheniramine, vitamin C, calcium and glucocorticoid can also be used to control and relieve symptoms. Avoid spicy food. Don't scratch, so as not to aggravate symptoms or secondary bacterial infection.

Specifically, doctors can guide drug treatment in the dermatological face-to-face consultation in the hospital.
