What is Delayed Pressure Urticaria

Delayed Pressure Urticaria (DPU) is a skin condition characterized by the development of itchy, red welts or hives on the skin after pressure is applied. These hives typically appear several hours after the pressure stimulus and can last for up to 48 hours. DPU is considered a form of physical urticaria, which means it is triggered by physical stimuli.

The exact cause of DPU is unknown, but it is believed to involve an abnormal immune response. Common triggers include tight clothing, standing or sitting for long periods, and activities that involve pressure on the skin, such as leaning on elbows or wearing tight shoes. The hives can be quite uncomfortable and may cause swelling, pain, or a burning sensation.

Treatment for DPU usually involves a combination of medications, such as antihistamines to relieve itching and inflammation, and corticosteroids to reduce swelling. Avoiding triggers and wearing loose-fitting clothing can also help manage symptoms. In severe cases, a doctor may recommend immunosuppressive medications or other therapies.

If you suspect you have DPU, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan.
