When I stumbled upon my first podcast with Dr. David Brady last year, I knew I had to bring his important message to the fibromyalgia community here at National Pain Report and to my readership at my blog, FedUpwithFatigue.com.
Dr. Brady’s message is one that I wish I had heard years ago when I was struggling with my first fibromyalgia symptoms, and it’s a message that hit me personally last spring when I was diagnosed with chronic Lyme disease.
So, what is this critical message? Based on the research and Dr. Brady’s many years of expertise, it’s incredibly likely that you don’t have fibromyalgia. Yeah, you read that right. According to at least one research study, up to two-thirds of us may have been misdiagnosed with fibromyalgia.
How it that possible? The fibromyalgia diagnosis criteria are so general that lots of people have been labeled with fibromyalgia when they actually have other conditions.
Think about the implications of that. What that means is that millions of us who have been diagnosed with fibromyalgia may not be receiving the correct treatment and we may even be living with treatable conditions.
The rampant misdiagnosis of fibromyalgia is one of the focuses of Dr. Brady’s new book, The Fibro Fix.
So, I bet you’re wondering: If you don’t have fibromyalgia, what else could it be? Read on for my interview with Dr. Brady. In our interview, we’ll discuss why fibromyalgia is so prone to overdiagnosis, and he’ll identify some of the most common conditions mislabeled as fibromyalgia. He’ll also explain the characteristics of true fibromyalgia and best practices for treatment.
I’ll warn you: The interview is long, but it’s well worth the read!
National Pain Report: You mentioned in a recent podcast that the diagnostic criteria for fibromyalgia make it prone to over-diagnosis. Can you elaborate on that?
Dr. Brady: The original diagnosis criteria for fibromyalgia [came out] in 1990, and it was established by an expert panel of rheumatologists with what was considered to be the best training and knowledge of fibromyalgia and global pain syndromes. It was called the ACR criteria for the American College of Rheumatology, and they basically locked a bunch of experts in a room and said they’re not coming out until they come up diagnostic criteria for this thing called fibromyalgia.
This panel of experts tried to codify what is fibromyalgia, what are the minimum criteria, and that’s where you got that first situation where the 18 points had to be challenged with pressure, and 11 out of 18 had to be positive [for a diagnosis of fibromyalgia].  It really was a negotiation in a conference room of how many points should you test, how many should be positive out of the number you tested, and it was not a very scientific process.
It basically resulted in criteria where people for various reasons who may have a lot of pain, particularly pain in the muscles around the body – even if it was caused by problems actually in the muscles themselves [like] some sort of myofascial pain syndrome or some sort of orthopedic or musculoskeletal problem – easily fit into that criteria. It was appreciated very early on that this criteria was very prone to overdiagnosis.
Then in about 2010, new modified criteria was again published by the American College of Rheumatology. It was subsequently modified a little bit in 2011, and the biggest change was they took away the requirement for the doctor to go around and challenge or push with pressure on all of these specific areas of the body. Instead they relied on a questionnaire where the patient checked [off] if they had pain in those areas, which is prone to even more overdiagnosis because it’s a subjective questionnaire.
The criteria did bring in a lot of the associated or concomitant issues that you see in fibromyalgia like depression, anxiety, unrefreshed sleep, irritable bowel syndrome, headaches, that the disorder had to be long-standing and chronic, meaning it had to be several months at least in duration, and that it couldn’t be explained by another medical condition.
Some people say it was a leap forward, and that’s what publishings by the American College of Rheumatology … suggest, although other studies suggest this criteria was also extremely prone to overdiagnosis. In a large study by [Mary Ann] Fitzcharles, one of the fibromyalgia experts in the world, using the original criteria, they found that if you had subjects who were diagnosed or labeled with fibromyalgia by family physicians, internal medicine doctors and even rheumatologists, when they were then sent to an expert panel of fibromyalgia rheumatologists, they only supported the original diagnosis of fibromyalgia about 33 percent of the time. What that means is 66 percent of patients diagnosed with fibromyalgia really didn’t have it! They had some other condition which was responsible for their symptoms. That’s worse than a coin flip, right? You’d be better off flipping a coin to determine if someone had fibromyalgia or not, so clearly it’s just not a good enough criteria.
Now there’s a brand new criteria that just came out in 2016. It’s only a mild tweaking of the 2011 criteria. It’s still prone to vast overdiagnosis. There’s still a lot of people who think they have fibromyalgia who do not. Saying that, I don’t want it to be misinterpreted that I’m doubting the sincerity of these folks and that I’m doubting that they have real problems because generally they do. Despite what some doctors might think, these people have better things to do in their lives than just make up these symptoms. They have real problems. They just don’t necessarily have fibromyalgia.
Aside from the diagnostic criteria, which is obviously flawed, are there other reasons people are way overdiagnosed with fibromyalgia?
Some of the symptoms that make up the profile of a fibromyalgia case are extremely ubiquitous in our population, meaning they are extremely common, like long-term persistent fatigue, achiness in the muscles, vague gastrointestinal complaints, mild depression, mild anxiety, insomnia. These things, taken individually, are extremely common. Therefore, when people tend to have a multitude of those problems that gang up on them, particularly if they are a woman in middle age, which is the prime potential person afflicted with fibromyalgia, there’s often a jumping to conclusions … that this person has fibromyalgia before they actually do a systematic workup … to really tease out … why are they fatigued, why do they have pain or achiness, why do they have insomnia, why do they have gut problems.
If you don’t run down all of the other causes for it, you really can’t diagnose fibromyalgia because one thing has been consistent among all the criteria over the years is it’s a diagnosis of exclusion. What we mean by that in medicine is that you have to first rule out every other potential cause of the symptoms before you would ever label it as fibromyalgia. Certainly, the layperson doesn’t do that, and unfortunately most physicians don’t do that before they put that label on somebody.
What are the most common conditions misdiagnosed as fibromyalgia?
I talk about what I call the triad of fibromyalgia masqueraders in my book, “The Fibro Fix.” The first one is actually an undiagnosed problem with thyroid function. It’s usually a hypothyroidism. It could be based in an autoimmune thyroid condition like Hashimoto’s disease, but it’s not always an overt, classic hypothyroidism that might be picked up by your family physician or by a conventional lab test just looking at a TSH level or a T4 level. Sometimes you have to dig a little deeper and look into thyroid physiology with a more complex understanding of it, on how the hormones are converted and how they work with the receptors.
A second one is when you’re having trouble in the cells of your body making energy or the currency of energy called ATP, or adenosine triphosphate, you’ll be energy deficient. Your cells will be starving for energy, and this occurs in little organelles in the cell called mitochondria. The mitochondria are like the little energy plants of the cells. They can be really damaged by things like long courses of antibiotics. Certain types of antibiotics, like the fluoroquinolone class of antibiotics, like Cipro, for instance, are really poisonous to mitochondria, but many other medications are harmful to mitochondria, including cholesterol-lowering drugs called statin drugs. They can really do a lot of damage to the mitochondria and the biochemistry of the mitochondria because they can cause profound CoQ10 deficiency, which is really important in mitochondrial biochemistry for energy production.
[Other causes for mitochondrial dysfunction include anemia and respiratory issues, like COPD.]
No. 3 is actual problems in the muscles themselves – what we call myofascial pain syndrome [and other musculoskeletal conditions]. This is where the problem actually resides in those somatic soft tissues around the body. Wherein true, classic fibromyalgia, even though you may be achy in the muscles, the problem is not in the muscles; the problem is in the brain. It’s in how your brain and the central nervous system interprets sensory information and sort of over-exaggerates or amplifies the information. If you really have fibromyalgia, therapies directed toward the muscles or the body – whether it’s massage or chiropractic manipulation or physical therapy or ultrasound or acupuncture – generally don’t help at all. The problem is not where they’re treating. The problem is deep in the brain.
If you have myofascial pain syndrome, those kinds of therapies do help a lot of people. If you really feel better and respond to those hands-on therapies, then your problem is not likely to be fibromyalgia. It’s more likely to be myofascial pain syndrome. And you’re not as likely to have things like anxiety, depression, unrefreshed sleep, even irritable bowel syndrome, as much.
[There’s a] fourth one I’ll throw in because it’s about to rise to the other three. [It’s the] misdiagnosis of Lyme and other tick-borne illnesses. These organisms can cause a lot of symptoms that can make someone be inappropriately labeled with fibromyalgia.
If someone is having fibromyalgia symptoms, what advice can you give to help them get the right diagnosis?
If you think you may have fibromyalgia, you have no choice other than to become a very informed healthcare consumer. You have to become essentially your best health advocate for yourself because the [healthcare] system generally is not going to do you much justice. You’re probably going to get mistreatment, misdiagnosis, [based on] what the averages say.
So I would start, and I say this honestly, not in a self-serving way, but I would probably start by reading my book, “The Fibro Fix,” because I wrote it just for this reason to educate people to be their own best health advocate.
If they think they might have fibromyalgia, [the book will help them] have a greater understanding of what fibromyalgia is, what it isn’t, what are the characteristics of real, classic fibromyalgia, what are the other things it might be and how they can start to differentiate for themselves what bucket or camp they might be in. We do that through a series of questionnaires and making you self-examine your situation, your past medical history, your stress situation and many other things to help you make that determination.
We try to guide you toward ways to find the right healthcare practitioner if you need help navigating this further. We give examples of what kinds of tests you might want to have them run and things to try on your own. The book is really about self-empowerment and everything you can do on your own to help recover from this situation that you find yourself in.
Also on my website, FibroFix.com, there are a lot of resources. There are questionnaires. There are diagnostic criteria. In the media tab, there’s also a lot of different interviews where I had time to go in-depth on some of these [issues]. I have some presentations there. I have articles and even medical papers I’ve written to help people learn as much as they can.
Also, last June I did a weeklong in-depth dive into fibromyalgia called the Fibro Fix Summit. I had about 35 experts from around the world in healthcare and also some patients who have a connection to fibromyalgia. Many of these experts are not only experts in fibromyalgia, but are experts in things that get misdiagnosed as fibromyalgia. I have experts in Lyme, I have experts in mitochondrial dysfunction, I have experts in thyroid, I have experts in myofascial pain syndrome. The Fibro Fix Summit is still available [via] digital access …or to order it on a flash drive.

Watch for Part 2 of Donna's interview with Dr. Brady later this week.

    This statement below is simply not proven and is another example of where people jump to conclusions.

    “No. 3 . . . . Wherein true, classic fibromyalgia, even though you may be achy in the muscles, the problem is not in the muscles; the problem is in the brain. It’s in how your brain and the central nervous system interprets sensory information and sort of over-exaggerates or amplifies the information. If you really have fibromyalgia, therapies directed toward the muscles or the body – whether it’s massage or chiropractic manipulation or physical therapy or ultrasound or acupuncture – generally don’t help at all. The problem is not where they’re treating. The problem is deep in the brain.”

    The cardinal symptom of the 33% is not pain, it is soft tissue stiffening. Soft-tissue stiffening produces pain. All pain is in the brain. People with FM may have a hypersensitivity to pain but that is different from “central sensitization” which postulates that the pain is “normal sensations interpreted as pain” and there is no “somatic” source or reason for the pain. Different analyses! My experience with properly diagnosed FM patients is that they have somatic sources of pain arising from various soft tissue and vascular changes. In all cases of “diagnosed FM” this needs to be properly investigated but is not being investigated because of the idea of central sensitization.

    This statement:
    “If you really have fibromyalgia, therapies directed toward the muscles or the body – whether it’s massage or chiropractic manipulation or physical therapy or ultrasound or acupuncture – generally don’t help at all.”

    is not totally correct. Many forms muscular therapy do help reduce pain in FM. Balneotherapy, vibrational massage, accupressure reduce pain in FM but it doesn’t last of course. The fact that these do reduce pain even for a short time suggests that the muscles are a source of pain. The writer also forgets another major symptom of FM: muscle spasms and cramps. These are some of the most disturbing symptoms which are not easily explained by central sensitization and are objectively observable.

    Why does exercise (when done correctly) in FM help reduce the pain? Because it improves blood supply to muscles and generally improves vascular function, also slowly relaxing muscle tissue – not because it reduces depression as the psychological/ central sensitization proponents argue.
