A numb feeling in the face, arms or legs can be a very serious signal, especially if the feeling is on one side of the body, as this could indicate a stroke.This symptom may be accompanied by sudden confusion, difficulty speaking or understanding, as well as blurred vision.
Numbness is also associated with several other illnesses, including Lyme disease, Guillain-Barre syndrome and diabetes, and a herniated disk.
If you are experiencing numbness in conjunction with other symptoms of a stroke, call 911 immediately.
