Raynaud's phenomenon

Raynaud's phenomenon is characterized by temporary blood vessel spasms in the fingers, toes, ears or nose, usually brought on by exposure to cold. Raynaud's phenomenon and Raynaud's disease, a similar disorder, may occur on their own or they may be associated with autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus, and scleroderma.
