Pressure urticaria is a skin condition characterized by the appearance of wheals or angioedema, deep swellings that occur after pressure has been applied to the skin. The pressure can be from tight clothing, sitting, walking, standing, or anything that puts pressure on the skin. The wheals or swellings can occur immediately or up to several hours after the pressure has been removed.
Symptoms[edit]
The main symptom of pressure urticaria is the appearance of deep, firm wheals or angioedema that occur after pressure has been applied to the skin. These wheals or swellings can be painful and may last for several hours to several days. Other symptoms may include fever, fatigue, and malaise.
Causes[edit]
The exact cause of pressure urticaria is unknown. However, it is thought to be related to an abnormal response of the immune system to pressure on the skin. Some people may have a genetic predisposition to the condition.
Diagnosis[edit]
Diagnosis of pressure urticaria is based on the patient's symptoms and medical history. A dermatologist may perform a pressure test, in which pressure is applied to the skin and the response is observed. Other tests may include a skin biopsy or blood tests to rule out other conditions.
Treatment[edit]
Treatment for pressure urticaria may include antihistamines to reduce itching and swelling, nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation, and corticosteroids to reduce inflammation. In severe cases, a type of medication called a biologic may be used.
