What is Nerve Root Compression (Radiculopathy)?
Cervical Nerve Root Compression, clinically known as Radiculopathy, refers the impaction or irritations of nerve roots as they exit the cervical spine. Typically, this will cause pain and neurological symptoms in the neck or arm. Patients will often describe pain in a specific distribution down their arm, or numbness, tingling or weakness of the affected arm.
Your doctor may have diagnosed you with cervical Radiculopathy, a Cervical Pinched Nerve or nerve root irritation, these are all similar terms for a Cervical Nerve Root Compression.
What are the main Symptoms of Cervical Nerve Root Compression?
Symptoms of Cervical Nerve Root Compression are can include pain and neurological symptoms:
- A Burning or searing pain, that can travel down one arm
- Numbness, tingling or ‘pins and needles’ down the arm or into the hand and fingers
- Weakness of certain parts of the shoulder, arm or hand, or difficulty moving your arm
- Abnormal reflexes when tested by a health professional
Why Are The Symptoms Down My Arm?
The cervical nerve roots at each spinal level, are distributed to convey the sensory information to the different areas of your arm. These distributions are called dermatomes, see the chart below. The specific nerve roots that are compressed or impacted, will alter the sensation or cause pain along these distributions. Likewise, each specific nerve root will innervate specific muscles in your arm. These specific groups of muscles and called myotomes, see the chart below. When a specific nerve root is compressed, muscles in this specific myotome may have reduced or no power.
As an example, a C6 Nerve Root Compression may cause someone to feel numbness in the thumb and/or weakness to the bicep muscle.

What causes Cervical Nerve Root Compression?
There is a large amount of conditions that can cause a Cervical Nerve Root Compression. Disc herniations, central spinal stenosis, osteophyte formation, spondylolisthesis or foraminal stenosis can all impact on the cervical nerve roots. It is this impaction or compression that causes the symptoms to occur.
