How to Identify It

Raynaud episodes typically follow a distinctive sequence:

White phase (paleness): Reduced blood flow makes the fingers look pale or completely white.

Blue phase (cyanosis): As oxygen levels in the tissues drop, the fingers can turn blue or purple.

Red phase (reactivation): When blood flow returns, the fingers become red and may feel warm, tingly, or painful.

Although Raynaud’s can appear on its own (primary Raynaud’s) without being linked to any other illness, it can also be a symptom of a more serious underlying condition (secondary Raynaud’s), such as autoimmune diseases or vascular disorders.
