The symptoms of a true herniated disc may not include back pain at all! The symptoms of a herniated disc come from pressure on, and irritation of, the nerves. In the thoracic spine area, this can include total paralysis of the legs. The symptoms of a herniated disc in the thoracic area, for example, usually include:

- Pain that travels around the body and into one or both legs
- Numbness or tingling in areas of one or both legs
- Muscle weakness in certain muscles of one or both legs
- Increased reflexes in one or both legs that can cause spasticity in the legs

Where these symptoms occur depends on which nerve(s) has been affected in the thoracic spine and whether the disc has ruptured enough to put pressure on the spinal cord itself. Where the symptoms occur helps your doctor with the diagnosis - to determine which disc has probably ruptured.

Irritation of motor neurons or motor axons can result in spontaneous discharge of individual motor axons and contraction of the motor unit. These can be seen on the skin surface as random, involuntary twitches that are termed fasciculations. Radiculopathy may cause irritation and lead to hyper-reflexia, fasciculations and other symptoms. An interesting fact is that most lower motor neurons are located in the cervical and lumbar spine.
