Although secondary Raynaud's is less common than the primary form, it tends to be a more serious disorder.

Raynaud's phenomenon occurs in the majority of people who have scleroderma - a rare disease that leads to hardening and scarring of the skin. Scleroderma, a type of connective tissue disease, results in Raynaud's because the disease reduces blood flow to the extremities.
