Arachnoiditis is a neuropathic disease caused by the
inflammation of the
arachnoid, one of the
membranes that surround and protect the
nerves of the central nervous system, including the brain and
spinal cord. The arachnoid can become inflamed because of an irritation from chemicals, infection from
bacteria or
viruses, as the result of direct injury to the spine, chronic compression of spinal nerves, or complications from spinal surgery or other invasive spinal procedures. Inflammation can sometimes lead to the formation of
scar tissue and adhesions which can cause the spinal nerves to "stick" together.
