A cervical traction pillow and an over-the-door neck traction unit can both be very helpful in stretching out the neck and minimizing pressure and pain in the spine. However, it is an ongoing process. You may notice some initial relief right away. But it can take anywhere from two to six weeks to see some long-term results. Like exercise and other stretching techniques, you should continue neck traction techniques on an ongoing basis to ensure maximum results. Regular neck traction exercises can lead to long-term relief of chronic neck and spinal pain.
