Beyond the Itch: Surprising Symptoms of Chronic Spontaneous Urticaria
Published: Aug 15, 2024
Chronic spontaneous urticaria (CSU) is known for causing itchy hives, but it can affect more than just your skin. Many people with CSU experience a range of other symptoms that aren't as well-known.
The Classic Signs
The hallmark symptoms of CSU are recurring hives (red, itchy welts) and angioedema (swelling under the skin). Hives typically appear and disappear within 24 hours, while angioedema can last longer. These symptoms come and go for at least 6 weeks without an obvious trigger.
Surprising Systemic Symptoms
Many people with CSU report systemic symptoms beyond skin issues. These can include fatigue, headaches, joint pain, and gastrointestinal problems. In one study, about 66% of CSU patients experienced systemic symptoms. These symptoms often correlate with more severe disease.
The Emotional Toll
CSU can significantly impact mental health and quality of life. Many patients report high levels of stress, anxiety, and depression related to their condition. The unpredictable nature of flare-ups can lead to social isolation and decreased work productivity.
When to See a Doctor
While CSU isn't usually dangerous, certain symptoms warrant immediate medical attention. These include difficulty breathing, dizziness, or swelling of the throat or tongue. It's also important to see a doctor if your hives last longer than 6 weeks or if you're experiencing systemic symptoms.
