Cervical Herniated Disc Signs And Symptoms - Spine-health

The cervical spine contains 7 vertebrae stacked atop each other, labeled C1 down to C7. The intervertebral discs are located between adjacent vertebral bodies. For example, the C5-C6 disc sits between the C5 and C6 vertebrae. If the C5-C6 disc herniates, it can compress a C6 nerve root. The signs and symptoms caused by a cervical herniated disc can vary depending on which nerve root is compressed. For example:

• C4-C5 (C5 nerve root): Pain, tingling, and/or numbness may radiate into the shoulder. Weakness may also be felt in the shoulder (deltoid muscle) and other muscles.

• C5-C6 (C6 nerve root): Pain, tingling, and/or numbness may be felt in the thumb side of the hand. Weakness may also be experienced in the biceps (muscles in the front of the upper arms) and wrist extensor muscles in the forearms. The C5-C6 disc is one of the most common to herniate.1Rainville J, et al. Comparison of symptoms from C6 and C7 radiculopathy. Spine (Phila Pa 1976). 2017; 42(20):1545-51. doi: 10.1097/BRS.0000000000002353.
• C6-C7 (C7 nerve root): Pain, tingling, and/or numbness may radiate into the hand and middle finger. Weakness may also be felt in the triceps (muscles in the back of the upper arm), finger extensors, and other muscles. The C6-C7 disc is commonly considered the most likely to herniate in the cervical spine.1Rainville J, et al. Comparison of symptoms from C6 and C7 radiculopathy. Spine (Phila Pa 1976). 2017; 42(20):1545-51. doi: 10.1097/BRS.0000000000002353.
• C7-T1 (C8 nerve root): Pain, tingling, and/or numbness may be felt in the outer forearm and pinky side of the hand. Weakness may also be experienced in finger flexors (handgrip) and other muscles.

These are typical pain patterns associated with a cervical disc herniation, but they are not absolute. Some people are simply wired differently than others, and therefore their arm pain and other symptoms will be different.
