Pain
Pain refers to an unpleasant sensation associated with actual or potential
tissue damage. There are many disorders which can result in pain including the
presence of inflammation, over stimulation of specialized nerve endings, and/or
direct nerve fiber compromise. Changes in bodily tissues which lead to the
subjective perception of pain are carried by specific nerve fibers to the brain
where the conscious appreciation of pain is influenced by many other factors.
Common causes of spine pain include inflammation, ischemia (lack of blood
flow), muscle spasm, nerve compression, disc herniation, and physical strain or
displacement of pain sensitive tissues.Abnormal spinal segment
movement may be associated with pain secondary to strain on supportive pain
sensitive tissues.
