A herniated disc at C6-C7 can cause a variety of symptoms. This condition is also known as a ruptured or slipped disc. The most common symptoms of a herniated disc at C6-C7 are numbness, weakness, pain and tingling. These symptoms occur due to pressure on the nerve root associated with the C6-C7 spinal disc in the neck.
Patients with a herniated disc at C6-C7 may experience tingling and numbness. According to the Chicago Institute of Neurosurgery and Neuroresearch, these symptoms are experienced in all fingertips and in the entire middle finger.
Weakness is another common symptom of a herniated disc at C6-C7. When this herniated disc presses on its associated nerves, the patient experiences weakness in the extension area of the wrist, according to the Chicago Institute of Neurosurgery and Neuroresearch. Spine-Health.com states that this weakness can also affect the triceps. The triceps are upper-arm muscles located in the back that extend to the forearm.
Patients with this condition may also experience pain, and, for some, this pain can become quite severe. The pain experienced when this cervical disc is herniated radiates down the muscles in the back of the upper arm (triceps) and down through the middle finger, according to Spine-Health.com.
