Cervical kyphosis ('reversed neck curve'): from AllAboutBackPain.com : --------- http://www.allaboutbackpain.com/html/spine_cervical/spine_cervical_kyphosis.html " Symptoms range from minor changes in the shape of your spine, to severe deformity, neurologic deficits, and chronic pain. Neck movement may become limited, making it difficult to turn the neck fully or to look up for very long. The abnormal forward curvature can eventually appear unattractive. Neck pain may be present, especially if the kyphosis is caused by degenerative changes. " If the kyphosis is severe, pressure can occur on the spinal nerve roots or spinal cord. This can cause weakness in the arms or legs, loss of grip strength, or difficulty walking due to spasticity in the legs. Bowel or bladder control may be lost. In extremely severe cases that are left untreated, paralysis from the neck down may even result." ---------- Note that they don't say anything about effects on other parts of the body (unless there's severe spinal cord damage). Chiropractors and other non-allopathic practitioners would have you believe that all KINDS of systemic disease can result from otherwise mild cases. Bogus!
