OBSOLETE: Vibratory angioedema

Vibratory angioedema is a rare condition where the skin reacts to vibration by swelling up. When something vibrates against the skin — like a lawnmower, a power tool, jogging, clapping, or even riding in a car — the body releases chemicals that cause swelling, redness, and itching in the area that was touched. This swelling is called angioedema, and in this condition it is specifically triggered by vibration. The condition is also sometimes called 'vibratory urticaria' because hives (urticaria) can appear alongside the swelling. The swelling usually happens within minutes of the vibration and goes away on its own within about an hour. It most often affects the hands, arms, and other areas that come into direct contact with vibrating surfaces. In most cases the reaction stays local, but in some people it can cause more widespread symptoms like flushing, headache, or a general feeling of being unwell. It is worth noting that Orphanet has marked this condition as 'obsolete,' meaning it may now be classified under a broader category such as inducible urticaria or physical urticaria. Treatment usually involves antihistamines to reduce symptoms and avoiding vibration triggers as much as possible. The condition is not life-threatening in most cases, but it can significantly affect daily activities and quality of life.
