How to Recognize and Treat Intractable Pain
/By Dr. Forest Tennant, PNN Columnist
The realization that a subgroup of chronic pain patients has intractable pain is finally spreading. Over half a dozen states now have laws protecting intractable pain (IP) patients and Wikipedia refers to IP as a disease that causes “a severe, constant, relentless, and debilitating pain.”
A major impediment to treatment of IP is simply that it is not commonly recognized by either patient or practitioner. Basically, the concept that pain alone can cause serious medical complications is not yet appreciated. This fact is evidenced in product advertising and lay person media articles about “chronic pain.” A close analysis implies that everyone has simple chronic pain and needs a “one size fits all” treatment.
The fact is that the IP subgroup of patients isn’t recognized by even the most sophisticated and prestigious medical institutions. For example, I hear almost daily about a person with IP who has severe hypertension, tachycardia, or even angina without any recognition that IP is the culprit.
Other examples are persons with IP who have hormonal deficiencies. Medical practitioners are treating their patients for such hormonal complications as osteoporosis, impotence, and depression, with no recognition that IP is the cause. Regrettably, some persons have had their pituitary or adrenal removed for a “tumor” when in reality the gland was over functioning and enlarged due to IP.
About half of the persons who develop IP have a genetic or inherited disorder. The most common high risk genetic conditions are Ehlers-Danlos Syndrome (EDS), ankylosing spondylitis, and scoliosis. Other genetic, but less common, risk disorders include Marfan Syndrome, porphyria, and autoimmune diseases such as rheumatoid arthritis and ulcerative colitis.
How IP Starts
Thanks to research and studies in recent years, there is now an understanding of the pathologic sequences that lead to IP. Basically, IP is the end product of multiple events and conditions that may affect a person.
IP always has a starting or painful initiating event which is either traumatic or inflammatory. Typically, the initiating event takes place several months or years before IP symptoms develop.
The most common traumatic events are falls, altercations or surgery. Trauma may be to the head, spinal cord, or a nerve in the arm or leg. The most common initiating inflammatory disorders are fibromyalgia, severe respiratory infection or arthritis.
The initiating event doesn’t usually cease but “smolders on” with pain that comes and goes. A diagnosis of chronic pain is likely assigned, and a wide variety of medications and other measures are attempted.
Interestingly, an initiating inflammatory event such as arthritis or fibromyalgia may seemingly spread. The person may develop additional inflammatory disorders such as thyroiditis, carpal tunnel syndrome, migraine, and irritable bowel.
Trauma may be severe or minor and the sequelae quite variable. Neuropathies or intervertebral disc degeneration and herniation are the most common traumatic complications that lead to IP. Pain after the initiating event is usually not constant, but at some point becomes constant.
This constancy is associated with inflammation that develops in the brain and/or spinal cord of the central nervous system (CNS). Cells called glia or microglia promote CNS inflammation, which can damage the neurotransmitter-receptor systems that control pain.
Exactly how injuries and inflammatory disorder activate glial cells to produce CNS is unclear. The two most discussed mechanisms are excess electromagnetic energy generated in the injury and inflammatory sites, and autoimmunity or viral invasion of CNS tissue. The Epstein Barr virus is the most likely virus.
The first chapters of my new book, “Handbook for Intractable Pain,” are dedicated to how to recognize IP symptoms. The second section is a step-by-step treatment program of self-help.
IP doesn’t have to thrust a person into misery and a short life if a three-component protocol is followed:
Suppression of inflammation and autoimmunity
Restoration of damaged tissues
Pain control
To carry out this protocol, one has to become knowledgeable about IP and build, over time, an effective therapeutic program.
