Health condition

Vibratory angioedema

Vibratory angioedema is a rare physical urticaria in which vibration - power tools, motorcycling, lawn mowing, even vigorous towelling - provokes localised swelling, itch and redness within minutes; a hereditary form caused by ADGRE2 mutations is recognised.

Key facts

The essentials at a glance.

The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.

  • Swelling, redness and itch develop within minutes of vibration exposure and typically settle within a few hours

  • Everyday triggers include power tools, motorcycle handlebars, lawnmowers, clapping and bumpy vehicle rides

  • A rare autosomal dominant hereditary form (ADGRE2 mutation) exists alongside acquired cases

  • Diagnosis uses a vortex vibration challenge; management is trigger reduction, anti-vibration equipment and antihistamines

Understanding the condition

What it is and what happens next.

What causes it, how it is diagnosed, and the treatment routes available in the UK.

What it is and how it feels

In vibratory angioedema, mast cells degranulate in direct response to mechanical shaking of the tissue, so the swelling maps precisely to what was vibrating - the hands and forearms after strimming, the thighs after a long ride. In occupational settings it overlaps with, and must be distinguished from, hand-arm vibration syndrome, which is a vascular and nerve injury rather than a mast-cell response.

Diagnosis and treatment routes

The diagnosis is confirmed by applying a laboratory vortex mixer to the forearm for a few minutes and observing the response, with family history guiding genetic considerations. Practical management - anti-vibration gloves, damped tools, task rotation - does most of the work, supported by second-generation antihistamines before predictable exposure; severe or occupationally limiting cases justify specialist review and workplace assessment. In much of the UK, a routine NHS referral to the relevant specialist clinic can take several months, whereas an initial appointment with a private consultant is typically available within around two weeks.

Seeing a specialist

Who to see, and how quickly you can be seen.

The specialist for this condition is usually a dermatologist or allergist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.

A quiet reminder

This guide is for information, not medical advice.

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.

Frequently asked

Common questions about Vibratory angioedema.

Quick, plain-English answers to what people ask us most.

  • What is vibratory angioedema?

    It is a rare form of physical urticaria/angioedema in which swelling occurs in response to vibration, such as from using a lawnmower, motorcycle, or even towel drying.

  • What causes vibratory angioedema?

    It results from mast cells in the skin releasing histamine and other substances in response to vibrational stimulation; a hereditary form involves a specific gene mutation, though sporadic (non-inherited) cases also occur.

  • What are the symptoms of vibratory angioedema?

    Localised swelling, redness, and itching or burning at the site exposed to vibration, developing within minutes and typically resolving within an hour or so.

  • Is vibratory angioedema dangerous?

    It's usually not dangerous, as swelling tends to be localised and self-limiting, though rarely more widespread reactions can occur, and it's worth having it properly assessed to exclude other causes of angioedema.

  • Is vibratory angioedema hereditary?

    There is a hereditary form caused by a specific gene mutation (ADGRE2), inherited in an autosomal dominant pattern, though sporadic, non-inherited cases also occur without a family history.

  • Can vibratory angioedema be treated?

    Yes, avoiding known vibration triggers where possible, along with antihistamines, can help manage symptoms; for more significant reactions, other treatments used for related mast cell conditions may be considered.

  • How is vibratory angioedema diagnosed?

    Diagnosis is often based on the characteristic history of swelling triggered by vibration, sometimes confirmed with a specific vibration challenge test performed under medical supervision.

  • Vibratory angioedema vs typical angioedema - what's the difference?

    Vibratory angioedema is specifically triggered by vibrational stimuli, while typical angioedema (allergic or hereditary) can be triggered by allergens, medications, or occur without an identifiable trigger; the specific vibration trigger history helps distinguish this rarer form.

  • When should I see an allergist, and how quickly can I be seen privately?

    See an allergist or immunologist if you notice swelling specifically triggered by vibration. NHS allergy clinic waits can be lengthy; private allergists can often see you within about two weeks.
