Many pathological processes can cause thoracic back pain. The list includes, but is not exhaustive:
Thoracic disc herniation is a rare condition. It comprises less the 1% of all disc herniations. Mostly it affects the lower part of the thoracic spine. Frequently the disc can be calcified.
Commonly, this condition is completely asymptomatic. However, in some cases it can cause pain which may be severe. The pain tends to radiate over the rib cage frequently following a course of an individual rib.
In some cases, thoracic disc herniation may cause compression of the spinal cord. This can lead to significant neurological deficit like sensory changes, numbness, tingling, pain, weakness, loss of bladder and bowel control, unsteady gait with poor balance and frequent falls. This condition requires urgent medical attention.
