What is a Pinched Nerve?

A pinched nerve occurs when a single nerve or group of nerves get compressed. This compression is often caused by pressure from bones, ligaments, tendons and even soft tissue that impinge or pinch the nerve. The medical term for a pinched nerve in the spine is Radiculopathy.

Your spinal cord extends from your brain and runs down your spinal canal through the center of your vertebrae. Nerve roots branch off your spinal cord and go between the vertebrae through small openings called foramina. These nerves travel to all ends of the body and transmit signals to the brain.

Our spines endure extreme pressure on a daily basis making them susceptible to injury. Sometimes this pressure or injury cause changes in the foramina resulting in radiculopathy, or a pinched nerve.

What are the symptoms of a Pinched Nerve?

pinched nerve

Pain is almost always associated with a pinched nerve. The pain from the compressed nerve correlates with the location of the radiculopathy. For example, a pinched nerve in the cervical spine might cause pain or tingling in the arms, elbows and hands, while a compressed nerve in the lumbar spine could cause radiating pain in the buttocks, legs and feet.

Pinched nerve symptoms include:

  • Sharp pain

  • Radiating pain

  • Aching or burning

  • Numbness or tingling

  • Decreased sensation in affected area

  • Weakness

  • Pins and needles sensation

If you think you could be experiencing symptoms related to radiculopathy.

What Causes A Pinched Nerve?

Pinched nerves are associated with, and often result of, many other conditions affecting the spine. Herniated discs are one of the most common causes of radiculopathy. Because of the close proximity of our discs and nerves within the spinal column, the bulging disc matter often pushes up on and compresses the adjacent nerve root.

Common causes of pinched nerves are:

  • Bone Spurs or Osteophytes

  • Degenerative Disc Disease

  • Herniated Disc

  • Bulging Disc

  • Slipped Disc

  • Arthritis

  • Poor Posture
  • Injury

  • Repetitive Motion or Overuse

  • Obesity

  • Genetics

  • Poor Health

Where is a pinched nerve usually located?

Pinched Nerve in the Cervical Spine

A compressed nerve in the cervical spine is often characterized by pain in the upper extremities and neck.

Patients complain of:

  • sharp neck pain
  • shoulder pain
  • arm pain
  • numbness in arms or hands
  • aching or burning pain
  • tingling or pins and needles in arms
  • pain when you turn your head

Pinched Nerve in the Lumbar Spine

The lumbar spine is the most common place to suffer from a compressed nerve. This area of the spine is the most flexible and carries the most stress and weight. It is also prone to degenerate more quickly than other areas.

Patients complain of:

  • sharp pain in the lower back
  • radiating pain that travels down the leg or into foot
  • pain the the buttocks
  • weakness in the legs
  • tingling or pins and needles in the legs
  • aching or burning pain

Pinched Nerve in the Thoracic Spine

A pinched nerve in the thoracic spine is more uncommon than in the lumbar and cervical regions and is often be misdiagnosed. It can also be linked to more serious conditions like myelopathy. Often caused by an acute injury or accident, a thoracic compressed nerve causes pain in the upper back, chest and torso.

Patients complain of:

  • radiating pain in the chest and back
  • weakness and shortness of breath
  • aching or burning pain
  • tingling or pins and needs

How is a pinched nerve diagnosed?

Patients who are suffering from symptoms associated with a pinched nerve receive a clinical examination as well as medical history overview. Upon completion, patients may be sent for imaging such as an MRI or CT Scan. Sometimes this involves injecting contrast dye called gadolinium into the bloodstream to give a clearer image of the blood vessels.

A nerve conduction study (NCS) may also be used to diagnose a compressed nerve. Also know as a nerve conduction velocity (NCV) test, this procedure measure how far and how fast electrical impulses move through the nerve by stimulating the nerve with electrodes. If the response is slow or stopped entirely, it may indicate a nerve injury like radiculopathy.

How is a pinched nerve treated?

Rest is the first treatment recommended for patients suffering from a compressed nerve. Therefore, discontinuing strenuous activities, especially those that cause pain is also suggested. If rest and relaxation do not solve the problem, the next step is conservative care. Conservative care options for radiculopathy are:

If conservative care does not help relieve the pain associated with a pinched nerve, minimally invasive surgical treatment may be recommended. Decompression procedures such as a laminectomy, laminotomy, or foraminotomy are all designed to relieve pressure by creating space for the nerve roots. These are minimally invasive and often performed in an outpatient facility. Many patients feel immediate relief following surgery.
