What Is Raynaud’s Phenomenon?
Raynaud’s phenomenon has the same symptoms as Raynaud’s disease, but its cause is known to be another disease. Diseases that can cause Raynaud’s phenomenon include rheumatoid arthritis, systemic lupus, and scleroderma, which are all chronic (long-lasting) disorders of the connective tissue*. Other possible causes include atherosclerosis (in which large arteries are blocked by fat deposits) and Buerger’s disease (in which small arteries in fingers and toes are blocked by inflammation).
