If you have been suffering from debilitating back pain and have difficulty walking, you may want to consult a doctor and rule out Cauda Equina syndrome. It is a rare disorder that affects the bundle of nerve roots at the lower end of the spinal cord. Some probable causes of this condition include a herniated disk, tumour, infection, fracture or narrowing of the spinal canal. The syndrome is difficult to diagnose as the symptoms take a long time to appear. Once diagnosed with the syndrome, you would need pain medicines, physical therapy and supportive braces to ease your pain.
