Raynaud’s Phenomenon

What is Raynaud’s Phenomenon?

---

Raynaud’s Phenomenon, sometimes known as Raynaud’s Syndrome, is a condition which impedes the supply of blood to certain parts of the body, such as the fingers and toes. It is common, affecting as much as 20 percent of the worldwide population, and sufferers may experience a number of symptoms, including discolouration, numbness, pain and/or difficulty performing certain tasks.

The condition is the result of blood vessels going into temporary spasm, restricting the blood flow. There are two types of Raynaud’s Phenomenon: primary and secondary. Primary Raynaud’s Phenomenon is the most common form and occurs by itself, as a result of disruptions in the nervous system. On the other hand, with secondary Raynaud’s Phenomenon, there is an underlying cause, such as a health condition, injury or harmful activity.

Raynaud’s Phenomenon can be triggered by a number of different things, including stress, anxiety, illness, infection, medication and exposure to cold temperatures. However, various occupations can also contribute to the development of Raynaud’s Phenomenon. In these instances, a sufferer may be able to make a successful compensation claim, as employers have a duty to protect the health of their staff.

Occupations which require excessive use of the hands may leave workers at risk of developing the condition as a result of overuse or injury. For example, it may affect people who need to type a lot, or musicians who need to use their hands to play an instrument for hours at a time.

What are the symptoms?

The most obvious symptom of Raynaud’s Phenomenon is a change in appearance of the affected part of the body. In stage one, the body part will turn white as blood flow is restricted. Stage two may then see it turn blue, as the body part is deprived of oxygen. Finally, in stage three, blood flow returns to the area at a quicker speed than normal, leading to redness of the skin.

In addition to changes in appearance, a number of physical symptoms may develop. In mild cases, an affected person may experience some numbness, pain, tingling or discomfort. In more severe cases, a sufferer may struggle to perform tasks which require precise movements. The condition may last anywhere from a few minutes to several hours.

Treatment of Raynaud’s Phenomenon varies depending on the cause, although self-help techniques, such as regular exercise to increase circulation, are often the primary treatment method. Medication, such as Nifedipine, may sometimes be required and in extreme cases, where there is a serious threat to the affected part of the body, surgery may even be necessary.
