Vibration white finger or vibration-induced white finger (VWF) is the vascular (blood and body fluid flow) component of HAVS. VWF is an industrial injury and classified as a form of Raynaud's syndrome.
VWF is characterized by episodes of blanching of fingers especially when exposed to cold. The other symptoms of HAVS such as numbness, tingling (parasthesia) and pain in the hands and fingers are now believed by many physicians to be a separate neurologic (nervous system) component of HAVS. The thumb is not normally affected. Smoking and stress may also aggravate the symptoms of HAVS.
The side effects of certain medications have been known to cause Raynaud's syndrome. In addition, various diseases, such as scleroderma, can have similar symptoms. These other causes must be ruled out before a diagnosis of VWF can be arrived at.
The symptoms of VWF are aggravated when the hands are exposed to cold. The development of HAVS is usually gradual and increases in severity over time. It may take a few months to several years for the symptoms of HAVS to become noticeable. HAVS is a progressive disease and when symptoms first appear, they may disappear after a short time. However, if exposure to vibration continues over months or years, the symptoms can become worse and become permanently present. In extreme cases, the sufferer may lose fingers.
