    GlossaryRaynaud's phenomenon

    condition where extremities' blood vessels overreact to cold or stress

    Raynaud's phenomenon is a condition where small blood vessels in extremities like fingers and toes constrict excessively in response to cold or stress, leading to color changes, numbness, and pain. It can occur on its own (primary Raynaud's) or be associated with other diseases (secondary Raynaud's), such as scleroderma or lupus.
