What does nerve root mean?
A nerve root in the spine is the part of the nerve that branches off from the spinal cord and enters into the intervertebral foramen (bony opening between adjacent vertebrae). Nerve roots help to innervate the side of the body where they are located.
What is a nerve root disorder?
Nerve root disorders result from sudden or long-term pressure on the spinal nerve root. Nerve root disorders usually result from a herniated disk or osteoarthritis in the spine. These disorders can cause pain, abnormal sensations, and/or muscle weakness in the area of the body they supply.
What does nerve root impingement mean?
Occasionally, a spinal nerve root is subjected to compression or irritation due to several factors. This compression is known as neural/nerve root impingement and can cause high discomfort such as loss of sensation and weakness.
What does a nerve root contain?
Sensory nerve roots contains nerve fibers that carry sensory information about such things as touch, position, pain, and temperature from the body to the spinal cord.) After exiting the spinal cord, the two nerve roots join to form a single spinal nerve.
How are nerve roots name?
The nerve roots are named for the level of the spine at which they exit. However, nerve roots are not labeled consistently throughout the length of the spine. In the cervical spine, the nerve root is named according to the LOWER spinal segment that the nerve root runs between.
How is nerve root damage diagnosed?
Diagnosis of Nerve Root Pain
- Spine MRI scan to determine soft tissue damage to the ligaments and discs, and assess spinal cord injury.
- X-rays to show the alignment of the bones along your neck and determine any narrowing or damage to the discs.
What are the symptoms of nerve damage?
The signs of nerve damage
- Numbness or tingling in the hands and feet.

- Regularly dropping objects that you’re holding.
- Sharp pains in your hands, arms, legs, or feet.
- A buzzing sensation that feels like a mild electrical shock.
What is the difference between a pinched nerve and impingement?
A pinched nerve is also referred to as nerve compression, nerve impingement, nerve root encroachment, radiculopathy and/or sciatica. However, all these terms don’t mean the same thing. Nerve impingement, or nerve entrapment, indicates that one single nerve is directly compressed.
What are the symptoms of nerve root compression?
These are some of the more common symptoms of compressed nerves:
- Pain in the area of compression, such as the neck or low back.
- Radiating pain, such as sciatica or radicular pain.
- Numbness or tingling.
- “Pins and needles” or a burning sensation.
- Weakness, especially with certain activities.

- Pain in the back, neck, and limbs.
What is difference between nerve and nerve root?
Thirty-one pairs of spinal nerves exit the spinal cord through openings between the vertebrae. The point at which a nerve exits the spinal cord is called a nerve root. The nerve root then branches out into many smaller peripheral nerves that control different parts of the body.
What can cause nerve root irritation and how is it treated?
We find one of the most common causes for recurring pain and injury is due to nerve root irritation not being fixed. For strong nerve root irritation some medications prescribed by your doctor may have good effect. These are normally specific low doses of anti-epileptic, or anti-depressant medications.
What are the symptoms of L4 and L5 nerve damage?
Pain. Pain may be the first indicator that you have a bulging disc at L4/5.
What is the treatment for nerve root compression?
The treatment of Nerve Root Compression is dependent on the severity of the compression and may vary from just pain medications, steroid administration and close observation to even surgical decompression of the nerve.
Depending on which nerve root is pinched, the following symptoms are likely: Pinched nerve at C5. This can cause shoulder pain, deltoid weakness, and possibly a small area of numbness in the shoulder. On physical exam, a patient’s biceps reflex may be diminished.
