Here is an effective cervical traction unit called the posture pump that I have recommended to many patients. Its called the arc4life posture pump:
The posture pump cervical traction device works to alleviate neck and shoulder pain. If you have been diagnosed with a disc issue such as disc bulge, stenosis or herniation and are looking for an alternative to neck surgery, you may want to explore this device.It can help to alleviate symptoms such as neck pain, muscle spasms, numbness, radiation into the fingers/hands, tingling sensation. One caveat - you may have soreness after you use this type of neck stretcher. Start very slowly - maybe you only traction your neck for 1-2 minutes the first day, and work up from there. You can avoid extra soreness by making sure you warm up your neck and shoulder muscles before starting. You will think its uncomfortable right in the beginning, but that will all change as your symptoms slowly start to dissipate. Dr. Bellinger mentions this in the video above.
