📋Overview
Raynaud's phenomenon is a condition characterized by episodic narrowing of small blood vessels, usually in the fingers and toes, leading to color changes, numbness, and discomfort. It is classified into primary (idiopathic) and secondary forms, the latter associated with underlying diseases such as autoimmune disorders. The term 'Raynaud's phenomenon' is the modern preferred terminology, replacing older eponyms like 'Raynaud's disease' when secondary causes are present.
