Have you ever experienced loss of sensation, tingling, or burning in any part of your body? If you have, you’re not alone.
Numbness is common. It often occurs due to actions, such as sitting cross-legged, that affect the nerves. According to the National Library of Medicine, over 20% of all people experience numbness and pain, and this percentage increases with age.
Most cases are not serious, and the feeling quickly dissipates with movement. However, prolonged or chronic numbness can occur and is usually a symptom of a more serious issue related to a neurological condition. Knowing if it is or not will require the diagnosis of a neurologist.
When should you call one? There are key signs that will indicate you need a neurologist. This article reviews some of the major ones.
Understanding Numbness
Numbness is a partial or complete loss of sensation in any part of the body. It occurs when persistent pressure, irritation, or damage to a particular nerve or several affects the flow of blood or nerve impulses. It is also referred to as paresthesia, a condition patients often describe as:
- An abnormal sensation
- Weakness
- Paralysis
- Tingling
- Burning
Often, these symptoms are temporary and resolve after moving the affected body part. However, persistent or chronic numbness lasts longer or does not go away. It usually indicates that the numbness is a symptom of a more serious condition.
Causes of Numbness
There are many reasons people experience numbness. The causes will vary depending on whether the numbness is temporary or chronic. Some of the main causes of temporary numbness include:
- Dehydration
- Whiplash
- Hyperventilation
- Seizures
- Migraines
- Panic attacks
- Nerve compression syndromes such as carpal tunnel syndrome
Moderate or severe nerve compression syndromes can become persistent, leading to chronic numbness. Issues related to the following can also cause persistent or chronic numbness:
- Circulatory system such as Renaud’s syndrome
- Nervous system, including brain tumors and bleeds
- Metabolic or endocrine systems such as menopause and low blood sugar
- Infectious diseases, including shingles
- Autoimmune and inflammatory diseases such as lupus and multiple sclerosis
Toxins and poisons can also affect the nervous system causing numbness. Some toxic sources include arsenic and carbon monoxide poisoning and venomous stings or bites from animals.
Key Signs Indicating the Need for a Neurologist
The inability to feel pain, light touches, temperature changes, or vibrations are common signs of numbness. But could they possibly be the onset of something more severe?
Knowing when to visit a neurologist is crucial to addressing this. Here are key signs that it’s time for specialized medical advice and care.
Sudden Onset of Numbness
Sudden numbness, especially on one side of the body could be a sign of a serious condition, possibly a stroke. If symptoms also include weakness or difficulty speaking immediate medical attention is necessary. According to the Merck Manual, sudden or rapid onset of numbness within minutes, hours, or days accompanied by weakness are of particular concern.
Accompanying Weakness or Paralysis
Why is numbness accompanied by weakness a red flag? Because these symptoms, along with paralysis, could indicate a serious condition such as:
- Stroke
- Spinal cord issues
- Multiple sclerosis
These neurological conditions require urgent care. According to the American Stroke Association, every minute that a stroke goes untreated, approximately 1.9 million brain cells die. Early treatment can increase survival rates and decrease disability rates.
Persistent or Worsening Numbness
Persistent or worsening numbness could lead to coordination or balance issues. It could affect your ability to walk and drive. You may also experience tingling, weakness, and paralysis.
Numbness can not only affect your quality of life, but could be a sign of neuropathy, herniated discs, or another condition.
An experienced neurologist can help determine the underlying cause and monitor symptom changes.
Other Neurological Symptoms
Symptoms may not only change, but they can increase as well. Patients may experience other symptoms, depending on the cause of the numbness. A few common ones include:
- Severe headaches or migraines
- Dizziness and balance issues
- Memory problems or cognitive changes
Although some of these can be debilitating, they can help pinpoint the underlying issue. They may signal a more serious neurological disorder.
What to Expect During a Neurological Evaluation
When you visit a neurologist, provide details of your symptoms. It’s important in determining an accurate diagnosis. They will also conduct a thorough examination including physical exams and diagnostics tests.
Initial Assessment
The neurologist will need a detailed medical history in addition to your list of symptoms. It will be a part of your initial assessment that will include a neurological exam to assess your:
- Motor skills
- Reflexes
- Coordination
- Sensory responses
The initial assessment helps the neurologist determine the diagnostic tests you will need.
Diagnostic Tests
Diagnostic tests help to diagnose the cause of numbness. Some of the more common ones you can expect your neurologist to perform include:
- Magnetic Resonance Imaging (MRI)
- A computerized tomography (CT) scan
- An Electromyography (EMG)
- Nerve conduction studies
The MRI and CT scans provide images of the brain and spinal cord and can show abnormalities, if any. The EMG measures electrical activity or muscle response. It can help determine if muscles are responding correctly to nerve signals.
Nerve conduction tests evaluate how well electrical signals move through the nerves. They help identify nerve damage.
Treating Numbness
Treatment will vary depending on the cause of your numbness. It is usually aimed at correcting the condition causing it. Your neurologist will provide nerve health tips to help avoid recurrence.
Chronic numbness solutions may also include:
- Vitamin supplements to treat vitamin deficiencies
- Physical therapy to help ease movement and strengthen the spine
- Nerve pain medication
- Regulating blood sugar in diabetic patients
For some patients, treatment may include surgery if they have a tumor or spinal problems.
