Why Should Everyone Care About Chronic Pain

Chronic pain is the in vogue topic of the day. It is a subject that has pushed its way into American’s awareness for very good reason. According to the American Academy of Pain Medicine, chronic pain currently affects more than 1.5 billion Americans, affecting work, sleep, and quality of life. Most importantly chronic pain has become dangerous as the opioid crisis has come to a head. Out of the 28,000 people who died of accidental drug overdose, nearly 12,000 died from pain killers, three times as many in 1999, according to the American Academy of Pain Medicine.

What Is Chronic Pain

Chronic pain is classically defined as pain that persists more than 3 months, but it is so much more than that. When pain becomes chronic, it is actually processed in the brain differently than acute pain. This is one of the reasons chronic pain has proven to be so difficult to treat using traditional means.

Pain serves a vital function and is something we need to survive. Pain alerts us to danger like a hot stove or broken bone and compels you to take action. This “take action now” pain is acute pain. Chronic pain lingers and can be totally independent of what is actually going on in the tissue. In fact, the tissue may have healed completely and still pain persists. There are a lot of thoughts as to why pain becomes chronic. It can seem like there is nothing left to treat, and all we can do is blunt it with analgesics and painkillers. But there is more to do. All pain, whether it is acute or chronic is processed by pain receptors, the spinal cord, and finally the brain. By addressing pain at the level of the nervous systems, we can change the way stimuli are perceived in the brain, and hopefully reduce pain.

The book, Explain Pain, by David Butler and Lorimer Moseley does a really superb job explaining this concept. In the book, they explain chronic pain is the body’s response to prolonged exposure to noxious stimuli. (In non medical person terms: basically if you have pain for a long time, the body becomes much more sensitive to things that may or may not be painful or damaging). In states of chronic pain, your body can actually lower the threshold for something to become considered painful in the brain. Meaning, that simple stimuli like tight fitting clothing, or sitting can feel very painful. Your body is doing this, because it is on guard for anything that might hurt it. Chronic pain is your body’s way of looking out for you, but has gone way too far.

This blog is not long enough to dig into all of the varied nuances of how and why chronic pain occurs, but if your interest is peaked, I would highly recommend taking a look at Explain Pain or The Explain Pain Protectometer in order to dig down into the deep and fascinating science behind chronic pain.

False Leads and Dead Ends In Pain

Opiods, Addiction, and Efficacy

The nature of chronic pain has proven to be elusive for patients and healthcare practitioners alike. In the 1990’s, in an effort to finally address chronic pain, opiods became much more widely used. At the time, drugs like Oxycontin were marketed as a safe way to treat chronic pain. The manufacturer of Oxycotin, Purdue Pharmaceuticals, instructed their drug representatives to tell doctors that the rate of addiction for long term Oxycotin users was 1%, according to pharma who help fund these studies. Although one study did indeed find these numbers many other found addiction rates in excess of 40%.

Probably one of the most unfortunate aspects of the push by pharma to prescribe opioids more freely, is despite marketing to the contrary, there have been more and more studies supporting the theory that opioids may in fact be ineffective for the treatment of chronic pain. Studies of worker’s compensation patients being treated for chronic pain indicate that patients on higher opioid dose, return to work more slowly than those on lower doses. Additionally, patients with back pain, who are being treated with long term opiod therapy report greater disability than those who are not on opioids.

Opiods have their place, especially in the treatment of cancer, procedural, and end of life pain, however it is becoming more and more clear that opiods are not the miracle drug we once thought they were in the treatment of long term chronic pain. The increased risks of addiction, accidental overdose, falls and fractures, depression, and severe constipation (which can indeed worsen the pain for which the opiod was prescribed in the first place), make it clear that as a medical community, we need to find a safer and more effective way to reduce chronic pain symptoms.

First steps

If you can find a cause, but at the same time don’t get hung up on it.

This is easier said than done. Often times, by the time patients reach us here at Beyond Basics Physical Therapy, they have folders that are stuffed to the brim with expensive diagnostic tests that read “unremarkable”. This can be incredibly frustrating for someone suffering with very real pain. My first word of advice is, If something doesn’t feel right with your body, don’t stop looking for help, until you find someone who can truly help you. There are many pain conditions like, chronic prostatitis and endometriosis. Which are poorly understood by many providers, that require treatment and or consultation by a specialist. This isn’t to say that the clinicians that are unfamiliar with chronic pain conditions aren’t fabulous providers, but these chronic pain conditions often require a clinician who spends his or her career treating and managing these type of pain syndromes. Basically, don’t allow yourself to be written off by any clinician who tries to tell you your pain isn’t real. It is, but most importantly there are things to be done. At Beyond Basics, we have extensive training on chronic pain conditions, additionally we have multiple connections with physicians, nurse practitioners, and other clinicians who treat chronic pain, that we will often refer too if we feel additional intervention beyond physical therapy is necessary.

I am warning you, before you read this paragraph, I am about to say something that on its face will seem mind numbingly contradictory. Bear with me please, and read the entire passage. If you do get a diagnosis, do not expect an immediate cure of pain. Chronic pain has gone past the point of solely being about tissue damage. A chronic undiagnosed infection, muscle spasm, or injury should be treated to remove the fire or proximate cause of the pain. Just because the pain is gone, does not mean the nervous system will immediately calm down. In chronic pain, treating the proximate cause enables the nervous system to begin to down regulate (or less threat sensitive) with further treatment, but does not always guarantee immediate cure.

This brings me to the problem with imaging. Imaging is a great tool and advances in the ubiquity and affordability of imaging techniques like ultrasound and magnetic resonance imaging (MRI), are allowing more and more people glimpses inside their body. If you have ever looked at an MRI of yourself the feeling is profound. I have been fortunate enough to see both my brain and right hip in mind blowing detail on MRI. It’s amazing, but sometimes knowing where every tear, herniation, and bit of swelling is not only unhelpful, but downright dangerous to some patients.

I am not being hyperbolic simply to drive a point home. Early and unindicated MRI in cases of low back pain has been shown to result in increased time spent on disability and increased cost of care ranging between $8,000-13,000 according to the article by Webster, cited in the sources. The fact is with imaging as powerful as MRI, we get to see almost EVERYTHING and because MRIs are getting slightly cheaper and more common, we are identifying structural changes like disc herniation in people, who might not have had a reason to suspect that there was something wrong in their spine in the first place. Sometimes knowing there is a structural abnormality in your body can cause pain and hypervigilance, when prior to knowing, you may not have had the same quality or as much pain in the first place.. Reports indicate that disc herniation and narrowing of the spinal cord can be seen in up to 57% of people who have no symptoms at all. It’s not a far leap to imagine someone with pain hanging all of their problems on a slipped disc if the MRI shows it. What’s worse, is MRI results are alluring and can often lead practitioners down the wrong path of treatment, because it is an easy answer.

In physical therapy school, my professors drilled into us, with almost religious fervor, treat what you find. A fabulous Physician’s Assistant of mine also told me 90% of what you need to know is in a patient’s history of their present illness. It is so true. You can tell a lot about the origin of the pain by asking questions like, how long has it been around, what makes it worse, what makes it better, and what does it feel like. Imaging can sometimes be a bit of a red herring, rushing well intentioned clinicians towards what they think is a cure, while skipping some crucial information through gathering steps that would aid in a more accurate diagnosis.

MRI’s aren’t all bad. They can be life saving and life improving when they are used appropriately. There are many clinical practice guidelines that guide providers on when it may be beneficial to order MRI or other imaging, however, research has certainly borne out that early imaging is actually counter productive in the treatment of chronic pain.

 

If you find a cause, great. If you don’t, or still feel bad don’t despair

We place so much of our hopes on diagnosis. It seems logical that if there is a cause, there must be a cure. Unfortunately, it is not alway so simple. We went over in the opening paragraphs about how chronic pain is more than what’s going on in a specific body part, it also involves the brain. Sometimes simply curing the tissues is not enough. Sometimes we never know what the cause is. This can be so frustrating for patients. As a pelvic pain specialist, I treat a lot of patients with pelvic floor pain and spasm, who have not yet figured out what specific incident brought the pain on. Rarely, in these cases, is there the “oh, crap” moment, when you realize you have injured yourself. Sometimes the development of chronic pain is like having a water glass. We are all born with water glasses of different sizes. We pour a little water in for something like poor posture, genetics, injury, diet, stress, etc., and when our water glass has overflowed, we develop chronic pain. There is no one definitive cause in cases of the overflowing water glass. Many factors have contributed, and many factors must be addressed in order to treat it properly. That’s why the holistic, mind-body approach is really where it’s at, when we treat chronic pain.

Now that you have a grasp on pain science and how chronic pain can behave differently from acute pain, you can begin to approach treating and dealing with it in a different way. In part two of this blog we will discuss different treatments for chronic pain, including yoga, acupuncture, meditation, of course, physical therapy, and many more. Please stay tuned.

    Thanks, Fiona, learned a lot. Pain certainly is a common part of life, especially as one gets older.
