One of the most common causes of neck and shoulder pain, headaches and migraines due to the loss of the cervical curve, meaning the spine of the neck has lost its normal backwards C shape and has either become too straight or even worse, bent backwards. This puts a lot of pressure on the muscles, ligaments and joints of the neck and manifests in many different ways but essentially the root cause of the problem needs to be addressed.
The Denneroll is the only tool I have found that actually corrects the cervical curve.
Stage 1: the rolled towel method is preparation for the Denneroll. If you can last 20 minutes on the rolled towel without any problems, then you can start supplementing in the Denneroll and slowly working your way up to 20 minutes on it.
