Back trouble is named chronic if it persists for more than three months continuously. The discomfort tends to reappear ever if an episode has been resolved. However the recurrence is irregular and variable.
Chronic back trouble can be categorized into 2 main types. The first type of prolonged back trouble has causes that definite causes such as spinal stenosis, and spondylolisthesis and degenerative disc disease. The second type of prolonged back stiffness does not have any such identifiable causes. In such cases of chronic back pain, the agony draws a trail in the nervous system. This interrupts the functioning of the nervous system and it sends wrong pain signals even if there’s no damage to the tissue.
