Vibratory angioedema is a skin condition characterized by the eruption of hives or itchy, raised welts as a result of vibration or repetitive rubbing of the skin. The skin contact that leads to hives may be from jogging, riding a bicycle or motorcycle, or rubbing oneself dry with a towel. The hives may also develop as a result of occupational exposures, such as power tools or other construction equipment. The hives may appear immediately after the vibration is applied or may appear hours to day later. They may go away within 30 to 60 minutes after they begin.
To diagnose vibratory angioedema, a doctor will obtain a medical history related to the appearance and onset of the hives. The doctor may apply vibrations or motions against the skin to confirm this as the cause of the skin reaction. Treatment for angioedema often includes antihistamines to reduce inflammation. If you have been diagnosed with vibratory angioedema, talk to your doctor about the most current treatment options. In addition, a genetic counselor can help discuss inheritance and risk to other family members.
