The spine is made up of the bones called vertebrae and a rubbery cushion between each vertebra called disks. A herniated disk occurs when the soft inner portion of the disk is pushed out through the exterior border of the disk. Herniated disk may occur in the neck or the back and often occur with trauma, or excessive strain.
Symptoms of a herniated disk usually occur on just one side of the body and vary depending on the location. Depending on the severity of the herniated disk there may be little to no pain to severe pain. Symptoms may also include sensory and or motor changes such as tingling, numbness and weakness.
