What Is Sciatica?

Posted by Illinois Back Institute on Wed, Oct 25, 2017 @ 05:07 PM

Sciatica.gifOver the years we've received a lot of emails from people who were asking, "What is Sciatica exactly?" So we're going to answer that question!

Exactly what IS Sciatica anyway?

First and foremost, it is important to define the term "Sciatica." Many people think Sciatica is the cause of their pain, but in actuality it is a symptom. There are multiple causes of Sciatica occurring.

The term Sciatica comes from the Sciatic Nerve, which runs from your lower spine all the way down your legs and to your feet. It is the largest nerve in the human body, and Sciatica occurs when this nerve is pinched. It's actually about as thick as your thumb! That explains why when it is pinched it can cause SEVERE pain.

  • sciatica_image_2-resized-600-1The Sciatic Nerve is so large because it is a combination of 5 different nerve roots

The Spine is made up of 24 vertebrae, and each of those vertebra is separated by a disc. Also, between each vertebra nerve roots exit off of the spinal cord and travel through the vertebrae and then throughout the body. These nerves are the communication pathways of the body. The nerves in the neck and upper spine travel into the arms and the nerves in the lower spine go into the legs.

To understand what these 5 nerve roots are and what they do, a brief description of the spine is necessary. Let's start at the top: the Brain. The brain is the information processing center, it sits on top of the spine, and is protected by the skull. At the very bottom of the brain is the brain stem, which is what connects the brain to the spinal cord as it enters the spine.

  • The five nerve roots that exit at the lowest part of the spine are: L4, L5, S1, S2, and S3
  • These five nerve roots join together after they exit the spine and form the Sciatic Nerve
  • When any of these five nerve roots get pinched, the result is Sciatica


Sciatica_2You are beginning to see how complicated Sciatica can be, since it can occur when any of those five nerve roots is pinched. Now you see that Sciatica is the "what", not the "why". The why comes from the symptoms associated with those five nerve roots, and each nerve root is associated with a different type of symptom.

Since the Sciatic Nerve begins in the lower back and travels all the way down the leg to the big toe, the most common symptom of Sciatica is pain that radiates down the leg.
