Cervical spondylitis n spondylosis are two different terms but are commonly used in place of each other. They produce similar symptoms and have similar causes.
All Neck pains are not cervical spondylitis. In almost half of the cases the problem is with the stiffness in the muscles of the cervical region.
Cervical spondylosis/spondylitis is a disorder caused by over-use, Mis-use or less-use of the structures in the neck (cervical). Due to this the ligaments, bones, cartilages, nerves, discs and muscles of the neck change their shape and strength. Bones become weak, irregular and develop spurs (osteophytes). Discs and muscles lose their flexibility and can pressurise the nerve.
