Lack of blood supply can also cause tingling and numbness to the extremities, reports MedlinePlus. Generalized numbness can be caused by vitamin deficiencies and abnormal levels of minerals and nutrients. If a supplement fails to eliminate the problem, a doctor may look for other symptoms that are associated with various medical conditions.

Numbness in the hands and feet is a common symptom of peripheral neuropathy, a disorder in which the nerves are damaged or destroyed, according to Healthline. Diabetes and physical injuries are common culprits of nerve damage, causing the nerves to malfunction by incorrectly sending, or failing to send, pain signals to the brain.

Another medical condition, Raynaud's phenomenon, describes the narrowing of blood vessels, usually concentrated in the hands and feet, according to MedlinePlus. The decreased blood flow can cause the extremities to feel cold and lose sensation.

Numb feet pose a minor health risk, cautions MedlinePlus. The lack of sensation increases risk of injury.
