Medicinal Diagnostics of Pain between Myth and Reality – Chronic Lower Back Pain, an Illness of the Upright Walk Chronic therapy-resistant low back pain is a major problem in medical care. In Germany there are many millions concerned, and the treatment expenses range at the top. Many of these patients underwent non-successful operations at the vertebral column and suffered a long-lasting odyssey of therapies before they are treated psychosomatically for the first time. Chronic low back pain is a disease including social, psychological as well as physiological aspects, and not only a problem of bones, muscles, or intervertebral disks. The problem is similar to that of fibromyalgia. On the basis of 9,000 case reports obtained during psychosomatic orthopedic treatment, character structures, unsolved problems of life and repressed emotional disturbances such as anger, jealousy, fear, and mourning could be identified as major psychosomatic risk factors for chronic low back pain. There is a high coincidence with other psychosomatically influenced diseases such as gastric and duodenal ulcera, asthma bronchiale, migraine with depressions, anxiety disorders, character neuroses, and narcissistic and other structural disturbances of the self. Exclusively somatic treatments without considering the existential situation and psychological methods hold the danger of a symptom shifting. The inpatient treatment from 9 a.m. to 5 p.m. (‘Tagesklinik’) with a combination of medical, physiotherapeutic and psychotherapeutic methods promotes a social training that counteracts the increasing constrictions in the accustomed life surroundings caused by low back pain. Chronic low back pain is an ‘illness of the upright walk’ in an anthropological, ethical sense. Considering low back pain as a strictly somatic disease is a modern myth of a medical treatment without existential understanding of human illness. It provokes failure of treatment and an enhancement of treatment cost.
