Neck pain (also known as cervicalgia or neck stiffness) may be caused by a misalignment of the cervical spine by known causes (hits, falls, motor vehicle accidents…). Cervicalgia may also have an unknown source (ignored bad postures, traumatic birth…).
The term neck stiffness is generally used to describe reduced flexibility of the neck, as noted by the person who suffers it.
If there is a lesion between the cervical vertebras that irritates a spinal nerve it may produce loss of touch as well as muscular weakness to the arms and hands. The cause may possibly be a herniated disc.
