What is Raynaud syndrome?
Raynaud syndrome ischaracterised by a discoloration of the fingers and toes, usually causing pain.

Causes
The discolorations and pain develop due to a sudden contraction of the muscles surrounding the small blood vessels which makes them narrower thereby decreasing the blood supply to the fingers and/or toes. The exact cause is not yet completely clear. The symptoms can be brought on by vibrations or by cold.

Raynaud's syndrome comprises both Raynaud disease, in where there are no other causes for the symptoms, and Raynaus phenomenon, in which the symptoms develop as a result of other diseases such as scleroderma and SLE. This form of Raynaud does not usually develop until after the age of 40, and can even lead to ulceration on the fingers.

Signs and symptoms
In Raynaud syndrome the fingers and/or the toes suddenly become cold and pale. They then turn blue and eventually, when 'warm' again, turn red. This may be accompanied by pain or a glowing sensation. The symptoms may persist for 5 to 30 minutes.
How is Raynaud syndrome diagnosed?
The diagnosis is made according to the patient's pattern of symptoms.
