Arachnoiditis describes a pain disorder caused by the inflammation of the arachnoid, one of the membranes that surround and protect the nerves of the 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 cause the spinal nerves to “stick” together. If arachnoiditis begins to interfere with the function of one or more of these nerves, it can cause a number of symptoms, including numbness, tingling, and a characteristic stinging and burning pain in the lower back or legs. Some people with arachnoiditis will have debilitating muscle cramps, twitches, or spasms. It may also affect bladder, bowel, and sexual function. In severe cases, arachnoiditis may cause paralysis of the lower limbs.

The meninges are composed of three layers, the dura mater and pia mater, and between these two, the arachnoid layer, so called because of the fine vessels in it resemble a spider's web. (Arachnida (Greek) = spider). Between the arachnoid layer and the pia mater is a small space, the sub-arachnoid space, which contains the cerebrospinal fluid.
While most cases of meningitis are caused by infectious agents, arachnoiditis is caused by surgical trauma, degenerative disc disease, rare infections, and spinal stenosis. It causes moderate to severe chronic pain, spasms and twitches.
