Numbness & Tingling

Numbness and tingling

Numbness and tingling are abnormal sensations that can occur anywhere in your body, but are often felt in your fingers, hands, feet, arms, or legs.

IF YOU OR SOMEONE YOU KNOW IS CONCERNED ABOUT HAVING NUMBNESS AND/OR TINGLING, PLEASE INQUIRE AT THE FRONT WINDOW ABOUT SCHEDULING A NEUROLOGICAL EVALUATION.

 

Causes

There are many possible causes of numbness and tingling:

  • Sitting or standing in the same position for a long time
  • Injuring a nerve (a neck injury may cause you to feel numbness anywhere along your arm or hand, while a low back injury can cause numbness or tingling down the back of your leg)
  • Pressure on the nerves of the spine, such as from a herniated disk
  • Pressure on peripheral nerves from enlarged blood vessels, tumors, scar tissue, or infection
  • Shingles or herpes zoster infection
  • Lack of blood supply to an area, such as from atherosclerosis, frostbite, or vessel inflammation (vasculitis)
  • Abnormal levels of calcium, potassium, or sodium in your body
  • A lack of vitamin B12 or other vitamin
  • Use of certain medications
  • Nerve damage due to lead, alcohol, tobacco or chemotherapy drugs
  • Radiation therapy
  • Animal bites
  • Insect, tick, mite, and spider bites
  • Seafood toxins

Numbness and tingling can be caused by other medical conditions, including:

  • Carpal tunnel syndrome (pressure on a nerve at the wrist)
  • Diabetes
  • Migraines
  • Multiple sclerosis
  • Seizures
  • Stroke
  • Transient ischemic attack (TIA), sometimes called a “mini-stroke”
  • Underactive thyroid
  • Raynaud’s phenomenon (narrowing of the blood vessels, usually in the hands and feet)

 

When to Contact a Medical Professional

Go to a hospital or call your local emergency number (such as 911) if:

  • You have weakness or are unable to move (paralysis), along with numbness or tingling
  • Numbness or tingling occur just after a head, neck, or back injury
  • You cannot control the movement of an arm or a leg or you have lost bladder or bowel control
  • You are confused or have lost consciousness, even briefly
  • You have slurred speech, a change in vision, difficulty walking, or weakness

Contact one of our neurologists if:

  • Numbness or tingling has no obvious cause (like a hand or foot “falling asleep”)
  • You have pain in your neck, forearm, or fingers
  • You are urinating more often
  • Numbness or tingling is in your legs and gets worse when you walk
  • You have a rash
  • You have dizziness, muscle spasm, or other unusual symptoms

 

Testing and Diagnosis

Blood tests may include:

  • Complete blood count or CBC
  • Electrolyte level (measurement of body chemicals and minerals) and liver function tests
  • Thyroid function tests
  • Measurement of vitamin levels
  • Heavy metal or toxicology screening
  • Sedimentation rate and measurements of c-reactive protein

Imaging tests may include:

  • Angiogram (a test that uses x-rays and a special dye to see inside the blood vessels)
  • CT angiogram
  • CT scan of the head
  • CT scan of the spine
  • MRI of the head
  • MRI of the spine
  • Ultrasound of neck vessels to determine your risk for TIA or stroke
  • Vascular ultrasound
  • X-ray of the affected area

Other tests that may be done include:

  • Electromyography and nerve conduction studies to measure how your muscles respond to nerve stimulation
  • Lumbar puncture (spinal tap) to rule out central nervous system disorders
  • Cold stimulation test may be done to check for Raynaud’s phenomenon
