4-Pain or stiffness in the back and neck
It can be located anywhere in the column; in the cervical area (where is the neck), in the dorsal area (upper back), in the lumbar region (where it is more common to injuries arising by a large amount of movement that occurs in this area) or in the sacral region (right on the sacrum, the bone that connects the spine with the lower half of the body). Generally, it is inflammatory back pain which occurs during the night, is not relieved by rest and, upon waking, often it accompanies a sense of rigidity which only decreases with exercise.
