Symptoms vary somewhat depending on the location of the injury. Spinal cord injury results in varying degress of weakness and sensory loss at and below the injury. The pattern depends on whether the entire cord is injured (complete) or only partially (incomplete).

The spinal cord doesn't go below the 1st lumbar vertebra, so injuries at and below this level do not cause spinal cord injury. However, they may cause "cauda equina syndrome" -- injury to the nerve roots in this area.
CERVICAL (NEAR THE NECK) INJURIES
When spinal cord injuries occur near the neck, varying degrees of symptoms can affect both the arms and the legs:
- weakness, paralysis
- breathing difficulties (from paralysis of the breathing muscles)
- spasticity (increased muscle tone)
- sensory changes
- numbness
- pain
- loss of normal bowel and bladder control (constipation, incontinence,
bladder spasms)
THORACIC (CHEST-LEVEL) INJURIES
When spinal injuries occur at chest level, varying degrees of symptoms can affect the legs:
- weakness, paralysis
- breathing difficulties (from paralysis of the breathing muscles)
- spasticity (increased muscle tone)
- sensory changes
- numbness
- pain
- loss of normal bowel and bladder control
- constipation
- incontinence
- bladder spasms
Injuries to the cervical or high thoracic cord may also result in:
- abnormal blood pressure
- blood pressure fluctuates quickly and through a wide range
- can be worsened with pain or bladder spasms
- abnormal sweating; trouble maintaining proper temperature
