Numbness in the feet can be caused by standing or sitting in the same position for long periods of time, by pressure or injury to a nerve, or by lack of blood supply to the affected area or vessel inflammation, states MedlinePlus. More serious chronic conditions may cause numb feet, including multiple sclerosis, stroke, migraines, underactive thyroid and seizure disorders.
Other potential causes of numbness include vitamin deficiencies and abnormal levels of certain nutrients such as calcium, sodium and potassium, notes MedlinePlus. Nerve damage caused by drug, tobacco and alcohol use or exposure to lead can cause the condition, as can radiation therapy and certain medications. Prescribed medications may require changes or adjustments, and vitamins may be prescribed for those who have deficiencies.
A series of tests is often necessary to accurately diagnose the underlying condition of numbness in the feet, including an angiogram, CT scan, MRI, ultrasound or X-ray of the affected area, according to MedlinePlus. Blood tests may also be needed, such as toxicology and heavy metal screening, complete blood count, electrolyte level and thyroid function tests.Learn more about Pain & Symptoms
