- Pressure from a tumor
- A hematoma (pooling blood)
- Slipped or bulging discs
A series of other diagnostic equipments and signs are necessary for determining injuries and illness of the spinal column, consisting of paralysis, bladder dysfunction, and gait disturbance, as well as diagnostic procedures such as imaging (MRI, CT, X-rays looking for bone damage) and blood tests (to look for infection).
