Pinched nerve facts

  • Nerve carry electrical signals from the brain to the body and vice-versa.
  • A pinched nerve can cause pain, numbness, tingling, or weakness along the path of the pinched nerve.
  • Most people improve from a pinched nerve with rest, ice, medication or physical therapy.
  • Weakness or wasting of the muscles from a pinched nerve can suggest permanent nerve injury.

Introduction to pinched nerve

Nerves are like electrical cords that carry information from the brain to the rest of the body and vice-versa. They are distributed throughout the entire body.

  • Motor (efferent) nerves carry information from the brain out to the body. This allows the brain to send commands to the various organs of the body. For example, these commands are sent to the muscles causing them to contract and move, or to the heart to either beat faster or slower.

  • Sensory (afferent) nerves send information from the body back to the brain for processing, including information about pain, touch, taste, temperature, or other sensations.

The information travels along the nerve by an electrochemical signal, much like information traveling along an electrical cord. When a nerve is pinched, the signal is interrupted somewhere along its path.

What causes a pinched nerve?

A pinched nerve is caused when a nerve is somehow damaged or injured by direct pressure or compression and is unable to properly conduct its signal. There are many potential causes for a pinched nerve, depending on the location of the nerve.

Pinched nerve in the neck or lower back

A pinched nerve in the neck or lower back can be caused by a herniated disc, arthritis, bone spurs, or spinal stenosis.

Spinal stenosis is a narrowing of the spinal canal through which the nerves pass with the spine. A pinched nerve in the lower back or buttock can compress the sciatic nerve, which can cause sciatica.
