What is neck nerve irritation (also known clinically as a cervical radiculopathy)?
Cervical nerves exit the neck at the levels of C1 – C8 (C8 nerve but there are only up to seven vertebrae in the neck).
They branch out supplying the muscles of the shoulder, arms, hand and fingers for functioning.
They also carry sensory fibers to the skin and muscles providing sensation.
Most commonly the lower neck joints can become affected by a herniated disc, neck spinal stenosis or disc degenerative disease which will cause nerve irritation and inflammation.
(Infrequently, cervical radiculopathy can be caused by other conditions, such as a tumor, fracture or sarcoidosis, which can compress or cause damage to the cervical nerve roots)
