There are many different symptoms that can stem from back pain and they each can mean different things:

• Changes in reflexes: Changes in reflexes, such as slower responses, can be a sign of spinal cord dysfunction.
• Uncontrolled muscle movement: Uncontrolled muscle movement is a common sign of a spinal cord disorder. You should have it evaluated by a spine specialist to determine what’s wrong. 
• Loss of sensation: Loss of sensation can be associated with spinal cord disorders and nerve compression. Loss of sensation could be numbness, tingling, or lack of feeling in some areas of the spine.
