Radicular pain can be produced in the dorsal region by the compression of a radicular nerve during its course from the medulla to its end. In this part of the spine, this compression manifests itself as a tingling sensation, numbness or a sensation of electricity (a term known as paresthesia or dysesthesia) which can be felt in different parts of the thorax, on one or two sides. This symptom can cause significant discomfort to the sufferer and can also alter the motor capacity of the area.

Generally this type of pain is produced as a consequence of the compression of one of the nerves that leave from the medulla to give sensory and motor capacity to the different parts of the thoracic region. Places where they can usually be compressed and causes:

• Intervertebral disc (due to protrusion or herniation).
• Due to the narrowing of the bony canal through which the nerves exit (known as the intervertebral foramen).

Depending on where it occurs, it may affect one area of the thorax or both:

• Pain
• Numbness
• Feeling of electricity
