Spinal decompression is a type of traction that may help relieve back pain and neck pain. Spinal decompression works by gently stretching the spine, which changes the force and position of the spine. This change takes pressure off of the spinal disks, which are gel-like cushions between the bones in your spine, by creating negative pressure in the disc. As a result, bulging or herniated disks may retract, taking pressure off nerves and other structures in your spine. This in turn, helps promote movement of water, oxygen, and nutrient-rich fluids into the disks so they can heal.
