When we speak about cervical, we mean a pain at the neck. The pain goes from the neck to the shoulders and, in more severe cases, to the arms making movements difficult.
The most frequent cause of cervical is the chronic contraction of the cervical muscles which is often accompanied to mandible malfunctions and cephalgia.
In most cases the pain stems from a light change of the muscles, of the ligaments, of the intervertrebal discs and of the back articulations that allow both the movement ( the neck has a high mobility so that the look can reach all directions) and the support (the neck supports the head which is very heavy).
Practically a mechanical stress which is too big and incorrect compared to the one the neck can support, causes a pain because the muscles contract and cause micro-damages.
Day after day these micro-damages may lead to a very common pathology: arthrosis. This disorder, which is linked to the wear of the cartilage of the joints and to the inter-vertrebal discs because of the age, is speeded up when you do incorrect movements for a long time
It is known the fact that the movements of the neck and the inflected extension movements tend to overload the cervical low area( C5-C6 rings) causing shoulder pain while a prolonged posture, for example in front of the screen, tends to overload the high cervical area (C1-C2 rings) causing headache ( of course each person can have an individual reaction ).
The automatic tendency to contract the muscles of the cervical area can also be due to a behavior already recorded in early childhood and it is independent from the voluntary control, as it may happen during the night.
