Degenerative disc disease treatment c5 c6 c7
Cervical degenerative disc disease is a common cause of neck pain and radiating arm pain. It develops when one or more of the cushioning discs in the cervical spine starts to break down due to wear and tear. There may be a genetic component that predisposes some people to more rapid wear. Injury may also accelerate and sometimes cause the development of degenerative changes.

Arm pain from a cervical herniated disc is one of the more common cervical spine conditions. It usually develops in the 30 – 50-year-old age group. Although a cervical herniated disc may originate from some sort of trauma or injury to the cervical spine, the symptoms commonly start spontaneously.
The arm pain from a cervical herniated disc results because the herniated disc material “pinches” or presses on a cervical nerve, causing pain to radiate along the nerve pathway down the arm. Along with the arm pain, numbness and tingling can be present down the arm and into the fingertips. Muscle weakness may also be present due to a cervical.
The two most common levels in the cervical spine to herniate are the C5 – C6 level (cervical 5 and cervical 6) and the C6 -C7 level. The next most common is the C4 – C5 level, and rarely the C7 – T1 level may herniate.
The nerve that is affected by the cervical disc herniation is the one exiting the spine at that level, so at the C5-C6 level, it is the C6 nerve root that is affected.
Symptoms of a Cervical Herniated Disc
A cervical herniated disc will typically cause pain patterns and neurological deficits as follows:
- C4 – C5 (C5 nerve root) – Can cause weakness in the deltoid muscle in the upper arm. Does not usually cause numbness or tingling. Can cause shoulder pain.
- C5 – C6 (C6 nerve root) – Can cause weakness in the biceps (muscles in the front of the upper arms) and wrist extensor muscles. Numbness and tingling along with pain can radiate to the thumb side of the hand. This is one of the most common levels for a cervical disc herniation to occur.
- C6 – C7 (C7 nerve root) – Can cause weakness in the triceps (muscles in the back of the upper arm and extending to the forearm) and the finger extensor muscles. Numbness and tingling along with pain can radiate down the triceps and into the middle finger. This is also one of the most common levels for a cervical disc herniation (see Figure 1).
- C7 – T1 (C8 nerve root) – Can cause weakness with handgrip. Numbness and tingling and pain can radiate down the arm to the little finger side of the hand.
It is important to note that the above list comprises typical pain patterns associated with a cervical disc herniation, but they are not absolute. Some people are simply wired up differently than others, and therefore their arm pain and other symptoms will be different.

Cervical Herniated Disc Symptoms and Treatment Options
The pain pattern from a cervical herniated disc is referred to as cervical radiculopathy.
Since there is not a lot of disc material between the vertebral bodies in the cervical spine, the discs are usually not very large. However, the space available for the nerves is also not that great, which means that even a small cervical disc herniation may impinge on the nerve and cause significant pain. The arm pain is usually most severe as the nerve first becomes pinched.
Cervical Herniated Disc Treatments
The majority of the time, the arm pain from a cervical herniated disc can be controlled with medication, and conservative (non-surgical) treatments alone are enough to resolve the condition.
Once the arm pain does start to improve it is unlikely to return, although it may take longer for the weakness and numbness/tingling to improve. If the arm pain gets better it is acceptable to continue with conservative treatment, as there really is no literature that supports the theory that surgery for cervical disc herniation helps the nerve root heal quicker.
All treatments for a cervical herniated disc are essentially designed to help resolve the arm pain, and usually, the weakness and numbness/tingling will resolve with time.
Cervical Degenerative Disc Disease
Cervical disc degeneration is a common cause of neck pain, most frequently felt as a stiff neck. Cervical degenerative disc disease is much less common than disc degeneration in the lumbar spine because the neck generally is subjected to far less torque and force. Nonetheless, a fall or a twisting injury to the disc space can spur degeneration, and accumulated wear and tear on the disc over time can also lead to neck pain caused by disc degeneration
In addition to having the low-grade pain of a stiff or inflexible neck, many patients with cervical disc degeneration have numbness, tingling, or even weakness in the neck, arms, or shoulders as a result of nerves in the cervical area becoming irritated or pinched.
For example, a pinched nerve root in the C6-C7 segment could result in weakness in the triceps and forearms, wrist drop, and altered sensation in the middle fingers or fingertips.
Cervical disc degeneration can also contribute to spinal stenosis (more specifically, the development of cervical stenosis) and other progressive conditions, as well as a more sudden disc herniation.
Successful diagnosis of cervical degenerative disc disease begins with a physician reviewing the patient’s history of symptoms and performing a physical examination to measure neck extension and flexibility. During the exam, patients may be asked to perform certain movements and report whether the neck pain increases or decreases.
If a physical exam warrants further investigation, imaging studies such as X-Ray, MRI, and possibly a CT scan will be taken. These diagnostic images can confirm whether and where degeneration is occurring and can identify other conditions (such as calcification or arthritis) that could be causing the symptoms.
