Typically, symptoms of nerve root irritation from C4 manifest themselves as shoulder pain. C4 refers to the 4th vertebra in the cervical region, where part of the phrenic nerve originates.
Cervical discectomies are done for cervical spine arthritis called as spondylosis. They are also done for compression of the spinal cord or a nerve root. If the discectomy is done from the front of the cervical spine, fusion is generally done. if the patient is young and disease is at single level, cervical disc replacement can also be done to avoid fusion and preserve motion, but studies say the outcomes are the same with both the procedures. If the nerve root compression is the only problem then the nerve root decompression can also be done by what is called as cervical formainotomy where the spine is approached from the back. If this procedure is done fusion is not necessary.
The nerves coming off the spinal cord at L5 and S1 are being pushed out of their normal position.
cervical disc hernia. first it compressed the dura mater, than the nerve root
The 31 pairs of spinal nerves are: 8 cervical 12 thoracic 5 lumbar 5 sacral 1 coccygeal. They are formed by the ventral and dorsal root of the nerve that comes out of the spinal cord.
The Greek root meaning nerve is "neur" or "neuro", which is commonly used in words related to the nervous system or nerve function.

Spinal nerve.....
The word root "cervical" pertains to the neck region or to the cervix of an organ.
Nerve root effacement refers to nerve root compression. This is an issue where the root of the nerve is compressed into the spine before exiting it, which can cause some painful back symptoms.
Cervical spondylosis refers to spondylosis of the cervical vertebrae (Bones of the spine in the region of the neck). Spondylosis refers to changes occurring in the bones ultimately resulting in compression of the nerve roots passing through these regions. The result of the nerve compression is determined by the specific nerve that is compressed. Common features include sharp pain radiating down the region of the upper limb supplied by the specific nerve root affected. Cervical spondylosis is common in older population. It is often due to osteoarthritis resulting in osteophyte formation (abnormal new bone growth) and these osteophytes result in the nerve compression.
