In brief: Blood vessel spasm

Raynaud’s is usually casued by exposure to cold temperatures (or emotional stress) that cause blood vessel spasms, usually in smaller blood vessels, such as in the fingers, toes, ears, and nose.
These areas will go through color changes first white (no blood flow), then blue (no oxygen) then red (return of flow), usually with pain or burning. Other causes can be some diseases, drugs, smoking.
