What Causes Numbness in Fingers and Feet?
Numbness is a symptom associated with a plethora of diseases and disorders. Transient numbness not accompanied by pain or changes in skin color may be a normal response to cold temperatures or other benign conditions. Persistent or recurrent numbness, however, always requires medical attention. Unless other symptoms are present, extensive testing and evaluation may be necessary before the underlying cause of the symptom is uncovered.
