Many of us assume that red pimples or rashes on the skin must be an allergic reaction to something we ate or applied. However, when this problem continues for weeks, dermatologists consider it a sign of a long-term condition called chronic spontaneous urticaria (CSU). It’s important to identify it early so that proper treatment can begin. Learn how to recognize it and when to be cautious.
The most common symptom of this condition is raised rashes on the skin. These rashes can be red or appear similar to your skin color. They are accompanied by intense itching. Notably, one rash subsides within a few hours, but a new one appears elsewhere on the body. If this has been happening for more than 6 weeks, consult a dermatologist. The itching bothers you more at night than during the day, disrupting sleep, and leaving you feeling tired the next day.
In a 2025 survey of CSU patients, more than half (62 percent) reported sleep problems during the worsening of the disease. Nearly half (49 percent) complained of fatigue. Therefore, if itching is disrupting your sleep and daily routine, don’t dismiss it as a minor issue.
Some patients also experience deep-seated swelling, called angioedema, which occurs in areas like the lips, eyelids, hands, and feet. It sometimes occurs with a rash, and sometimes alone. If the swelling recurs, you should consult a specialist. If you experience difficulty breathing or swallowing, or if you notice swelling in the tongue or throat, seek emergency medical attention without delay. A specific cause is often elusive, so blaming a specific food or cream and abandoning medication is not a good idea.
When rashes and swelling appear repeatedly, you may feel hesitant to face people. There’s a constant worry about when the itching will start again. If this condition persists for a long time, it can lead to increased stress. Don’t put off treatment due to embarrassment or fear. Consult a dermatologist or allergist. With proper treatment, symptoms can be kept under control.
