AA will be the term used throughout this paper as it is this stage of the disease that usually causes a patient to seek medical and pain treatment. It is worth remembering that cauda equina syndrome is a clinical diagnosis and thus the term should not be used in a radiology report unless the appropriate symptoms and signs are known. Adhesive arachnoiditis can potentially lead to disability. Patients develop a high prevalence of arthralgia, myalgia, and such autoimmune phenomenon as Hashimotos thyroiditis and carpal tunnel syndrome. Although the mechanism for the development of autoimmune symptoms is unknown, a possible explanation is the drainage of cells and soluble antigens in the spinal fluid into regional lymph nodes. A major treatment goal is to stop the progression, disability, and deterioration that is characteristic of AA patients. Severe cases may require high-dose opioid therapy.

To illustrate, a case report is given here with the patients chronic management program included. The protocol comprises 4 components: (1) control and suppression of neuroinflammation; (2) exercises to prevent adhesions; (3) pain relief; and (4) neuroprotection and neurogenesis (nerve growth) (Table 2).
