Understanding the problem begins with understanding the anatomy of the spinal canal . The spinal cord and the contained nerves travel from the brain to the lower spine region. The nerves exit the spinal cord at the appropriate levels. The nerve roots are encased by membranes which protect and nourish the nerves. These membranes are very delicate and easily injured.
Later stages can cause pain.
People who have arachnoiditis describe the pain as a burning type pain. The pain is located in the lower back region and often times radiates into the legs. Frequently it persists while resting. Arachnoiditis can also cause neurologic dysfunction. The causes of arachnoiditis include tuberculosis , meningitis , syphilis , ankylosing spondylitis, syringomyelelia, epidural anesthesia analgesia, epidural blocks, spine surgery, and myelographic studies.
