Raynaud's-disease affects about 5-8 per cent of the population, one third of the patients are women.

During the course of the disease fingers of the hand (rarely the foot) suddenly become painful pale or white under cold or after psychological or emotional trauma. The cause of this is that vessels in the fingers constrict thus blood flows out of them suddenly.

This is followed by the second phase when blood circulation starts again in fingers – this time fingers become purple-colored.

In the third phase pain ceases and fingers become red.

Certain medications (beta-blockers, chemotherapy drugs, oral contraceptives) may also trigger the complaints.

Treatment: cessation of smoking, warm clothing, protection against injuries, vasodilator medications. In severe cases surgery may also be an option.
