Unlike herniated discs in other areas of the spine, a thoracic herniated disc usually produces no symptoms. They are usually diagnosed by chance if an MRI is performed for something else. Most thoracic disc herniations occur in the lower half of the area, since the upper half has very limited mobility. Most herniated discs are the result of natural disc degeneration, but can also be the result of trauma. Although symptoms are rare, they often include pain radiating as a band around the chest. Treatment for a thoracic herniated disc includes immobilization of the back, medication, or surgery.
