What is arachnoiditis?

Arachnoiditis is a pain disorder caused by the inflammation of the arachnoid, one of the membranes that surround and protect the nerves of the spinal cord. Severe stinging, a “burning” pain, and neurological problems characterize the condition. Inflammation (swelling) of the arachnoid can lead to the formation of scar tissue and can cause the spinal nerves to stick together and malfunction (not work properly).
