A groundbreaking new study paves the way for future treatments for fibromyalgia

Hey everyone!

If you’ve been following my blog for a while, you’ve probably seen this absolutely incredible TED talk by Dr. Elliot Krane, on the nature of chronic pain.  It is seriously one of my favorite things to watch.  Chronic pain is terrible, but it’s always so hopeful to me to keep track of how much we’re learning through scientific research.

One of the things Dr. Krane mentions in this talk, which was back in 2011, is the role of a type of nervous system cell called a glial cell in chronic pain.

For a long time, scientists didn’t think glial cells did that much, in terms of affecting our overall function.  Instead, glial cells were believed to provide a supportive rule, providing support and nutrients to other types of cells within the nervous system.

However, a new line of research has been identifying the fact that glial cells actually do way more than we give them credit for, in their own right.

Fast forward to 2018: turns out researchers at Massachusetts General Hospital as well as the Karolinska Institute in Sweden have just published a groundbreaking new study on the role of glial cells in chronic pain.

For this study, researchers used brain imaging techniques to test for the level of TSPO, a chemical related to the activity of glial cells, in several different parts of the brain.  They compared the level of this chemical in the brains of patients with fibromyalgia, as well as the brains of healthy subjects for comparison.

Not only did they find that fibromyalgia sufferers had much higher levels of the marker, but they also found that the amounts of this chemical present– and therefore, the level of glial cell activity– was actually correlated with the amount of fatigue reported by patients.

This is super fascinating because it shows that glial cell activity plays a role not just in our perception of pain and pain sensitization, but also in the debilitating fatigue that many fibromyalgia sufferers report.

Because a study like this is able to demonstrate this link so clearly, that opens the door for researchers to further investigate drug therapies which can target the glial cells, meaning we will someday have more options for chronic pain.

You can check out the original study here.

I am excited about this, so I wanted to be sure to pass it on.

Happy Monday to you all!

When the going gets tough, the tough start researching…

Hi everyone!

Today I wanted to share with you this post from my friend Clare over at Jelly-Like Joints.

Clare is a science-lover and “bookish crafter” –a book lover who also enjoys arts and crafts.   She was born with a genetic condition that affects her connective tissues.   This causes her to have hypermobile joints, along with chronic pain and other symptoms.

In her post, Clare writes about how she’s been struggling with some new symptoms lately, specifically in regards to her voice.  (Connective tissue disorders can cause a wide range of symptoms, because connective tissue can be found just about everywhere in your body).

I wanted to share her post with you because I really admired her mindset– it’s the approach I try to take as well, when I have setbacks.

Which is to take a step back and say, ok.  I have this new problem I wasn’t expecting.  But that also means there are new potential solutions out there I haven’t tried.

Of course, this is easier said than done.  And I admit, it is not always my immediate reaction.  But when I work through the anger and frustration, this is usually the point I get to that feels right, that lets me know I’m on the right path.

Keep going.  Don’t stop looking for answers.

So what I really admired about Clare’s post is how, not only is she mentioning things that could be helpful to her, she keeps trying to help others at the same time.

So… check out her post!

You may notice that she’s included a link to one of my blog posts ;) I also struggle with hypermobile joints, however mine are hypermobile for a different reason.  I am very fortunate not to have a connective tissue disorder…  I was just born with joints that don’t fit together in the most stable way, making them more prone to pain and potential injury.  (It just happens to some people, through luck of the genetic lottery).

I also really thought the part about the acupressure mat was interesting.  For those that don’t know, the term proprioception means a general awareness of where your body is in space, and the different stimuli affecting it.  Our sense of balance, for example, depends on different types of proprioceptive input through our nervous system.

Sometimes when we have a chronic illness, or injury, or chronic pain, our sense of proprioception to different parts of our body can be impeded, so an important part of therapy is to help the nervous system “remember” to check for different types of information.

That is something the acupressure mat could do, by giving TONS of information to our nervous system about what’s going on with your feet!  So I thought that was cool.

Anyway, I hope you’re doing well, and that you all head on over to check out Jelly-Like Joints!

Too much of a good thing: when people don’t really *get* pain science

I wanted to share a really important post with you all this morning, from the author of Chronically Undiagnosed.

She’s a therapist who is dealing with chronic illness.  Recently, she wrote about her experience attending a chronic pain support group that incorporated some of the theories of modern pain science… but did so very badly.

As someone who fervently believes in what pain science has to offer — it’s what originally inspired me to become a physical therapist– I have often felt many of her same frustrations, when people try to stretch pain science beyond the limits of its intended applications, or when they lump in their own personal beliefs about pain which have nothing to do with the actual scientific literature on the subject.

Reading her post, it sounds as though the social worker leading the class did have a basic understanding of pain science.

(By modern pain science, I mean the school of thought that says that pain is a function of our brains that’s meant to protect us, and as a protective mechanism, it doesn’t always work perfectly, or give us an accurate way to gauge what’s actually happening in our bodies. People can experience devastating injuries and feel no pain, or they can experience excruciating pain from injuries that are technically “minor.”  Pain scientists believe this knowledge can help us develop new treatment approaches, once we begin to tap into the fact that pain is here to protect us.  Some of the original proponents of this approach include David Butler and Lorimer Moseley).

It sounds as though Chronically Undiagnosed’s group leader did present some of these anecdotes, to prove that pain can be subjective.  But she did so in a way that was alienating to the group participants.

Chronically Undiagnosed writes:

“The instructors have cited reports of individuals who have either been injured and experienced no pain, or individuals who thought they were injured (but were not) and experienced extreme pain. One example was of a roofer who landed on a 6-inch nail that went through his steel toed boot who presented in the E.R with reports of excruciating pain. He was medicated for pain and the boot removed where it was discovered that the nail had gone through his shoe but between his toes, resulting in zero tissue damage. Additionally pictures of MRI’s were shown where a person had visible spine damage but no pain.

As someone with an advanced degree who has studied and taught research and statistics, I find fault with their examples. In a scientifically based research study, extreme results such as these are considered “outliers” and are not considered statistically significant. And as someone who has both counseled patients with chronic pain and experienced it daily for over 5 years, I find their assumptions to be not only scientifically incorrect but harmful to people experiencing chronic pain.

And now here come the people touting “modern pain science” as a breakthrough in treating pain. If pain is simply a perception created by the brain, then if we change our brains the pain should go away. When I expressed my concerns to the leader of the group she suggested that leading medical institutions in our country (such as Stanford, where I received “injections” that helped me) are “behind” in understanding pain.”

Reading about her experience made me really frustrated and sad, because I had a totally opposite experience when first presented with this information.

However, when I first came across it (under the guidance of my physical therapist Tim, and through watching physiotherapist Neil Pearson‘s lectures) I understood these stories– which ARE statistical outliers– to simply be examples illustrating how pain works.

They are extreme examples, but they demonstrate the fact that pain does not always provide an accurate indication of what is wrong in our bodies.  These stories are meant to educate, not to give people the impression that they ought to be able to magically “turn off” the pain in their brains tomorrow.

Following this, it sounds as though the social worker leading the group made another key mistake, one that I absolutely can’t stand:

She lumped her own personal beliefs about pain in with the theories of modern pain science, without making any distinction in between the two.

I’ve personally seen this before.  The first doctor who ever told me I had a heightened sensitivity to pain never actually told me about any of the neuroscience research behind this phenomenon (central sensitization).  Instead, she told me I was probably suffering from some form of psychological trauma, and that the only way for me to get better was through psychotherapy.

Years later, when I had finally discovered pain neurophysiology education, I found that the people actually researching modern pain science never talked about childhood trauma (or any other kind of psychological trauma).  They didn’t need to– the theory of pain as an imperfect protective mechanism was enough to explain so many of the things that could sometimes go wrong with it.

That’s not to say that no one, ever, experiences physical pain as a result of emotional trauma.  That’s not what I’m trying to say either.  But it’s wrong to be leading a group where you’re presenting people with the theories of modern pain science, and lump in your own personal beliefs about pain without making a distinction.

She did actually lump in other grains of truth.

Some of the other information Chronically Undiagnosed’s social worker presented is, technically, legitimate.

It is true that MRI’s are not always the best predictors of who will actually experience back pain.  There’s a great book, Back Sense, that talks about this.

In a nutshell, if you were to take 100 people off the street and take an MRI of everyone’s spine, you wouldn’t necessarily be able to tell, just by looking at the MRI’s, who was actually experiencing back pain.

We all experience some degeneration to our spines over time, but sometimes this degeneration can be symptom-less.

However, this information should never be used to tell a group of chronic pain patients they shouldn’t be experiencing any pain!

All of these bits of knowledge, which can be helpful– whether it’s pain science, or Back Sense– are meant to be one piece of the puzzle!

And they are meant to help illuminate aspects of patients’ experience.  They are meant to educate.  

They are not meant to blame people, or make them feel responsible for experiencing pain they shouldn’t be feeling!

I see this far too often in the field of pain science.

As a (hopeful) future physical therapist, I’ve followed a number of physical therapists, writers, and researchers on various social media platforms, hoping to learn more about how the field of pain science is evolving.

Unfortunately, I’ve had to go back and actually “unfollow” a bunch of people, because I see the same thing over and over again.  People will get annoyed and actually downright snarky about patients and fellow medical professionals trying to treat certain conditions which are the subject of controversy– the sort of “gray areas.”

One of these areas, in particular, is the sacroiliac joint.  There are a lot of physical therapists out there who don’t believe sacroiliac joint dysfunction is a real thing.

So I’ll sign on to Twitter, and find that someone I respected and followed to learn more about pain science is tweeting out some kind of derogatory commentary about how “the sacroiliac joint doesn’t really move” and what a “sham” it is that people are trying to treat it.

I suppose the evidence for sacroiliac joint dysfunction is really a topic for another post, however to me it’s just another example of people trying to take pain science too far.

Ultimately, I believe these physical therapists’ anger stems from a good place.  From their perspective, they’re probably tired of seeing other medical professionals “waste” patients’ time by treating them for musculoskeletal causes of pain, when they should be focusing on the nervous system.

But really, there are two sides of the same coin.

Yes, pain originates in our brains.  And our brains can shut pain off, in emergency situations.  

But that doesn’t mean patients’ pain isn’t valid.  That doesn’t mean that, once you put them in a 3-hour class where they hear about extreme examples of people not experiencing pain, they should automatically be able to “turn off” their own pain.

No approach will work if you don’t listen to people.  No approach will work if you aren’t kind.  That’s really the bottom line.

Pain science should be used to educate– not to deny the other potential reasons someone could be experiencing pain.

Just as MRI’s aren’t always accurate indicators of who will have back pain, it doesn’t mean that someone in excruciating pain shouldn’t have an MRI.

All of these things represent aspects of the truth, but no one piece should ever be a substitute for looking at the whole picture.

P.S. Please don’t worry, there are plenty of ways to learn about pain science from people who actually do get it!

I also highly recommend Todd Hargrove’s article Seven Things You Should Know About Pain Science.

 

The Four Categories of Pain– Dr. Jay Joshi

Hi everyone!

I’ve just discovered this awesome talk on central sensitization by pain management physician Dr. Jay Joshi.  It’s totally packed with information I want to share with you all– such as why it’s so hard to get help for central sensitization, and how ketamine infusion treatments can help.  There’s so much here, though, that I thought I’d break it down into bite-sized information for you.

So, to start out, let’s look at what Dr. Joshi says are the four main types of pain.  (For the purposes of this blog post, I’m actually jumping ahead to the 8:50 mark– later, we’ll come back to the beginning).  

The four types:

  1. Nociceptive
  2. Neuropathic
  3. Inflammatory
  4. Central Sensitization

1. Nociceptive pain: pain that results from actual tissue damage, or potential tissue damage (like if you’re starting to bend a joint past its normal range of motion).  It is “the common discomfort we have all experienced as a result of injury — a paper cut, a broken bone, or appendicitis, among other things.

More on nociceptive pain and its subtypes

2. Neuropathic pain: involves physical damage to the nerves or the central nervous system itself.  It can also occur when the person has a tumor that’s pressing upon a nerve.

3. Inflammatory Pain: Pain produced by the chemicals our body releases as part of the inflammatory or healing process.  On a small scale, think of how a bruise swells up and is painful to the touch.  This is because our body is sending special cells and chemical messengers to that part of our body in order to heal it– and also to make it painful, so that we know to protect the area.  This is inflammatory pain, and it can also happen on a much larger scale with more serious injuries.

4. Central Sensitization: And here we are– the type of pain that’s most affected my life.  It has to do with the concept of neuroplasticity: that the central nervous system (the brain and spinal cord) can change in response to the things it experiences.

When your body experiences a painful event or an injury, it learns from that experience, the same way it learns from anything.  Practice makes perfect– when your brain gets enough practice at sending pain signals, it gets better at it gets better at it.  In a way, this is for your protection– you learn and become more sensitive to performing the same kinds of actions or motions that may have caused this injury in the first place.

However, as a protective mechanism, central sensitization can sort of backfire.  Eventually, we can reach a point where our nervous systems are trying to protect us too much, when we’re not really at risk of injury anymore.

So these are the four main types.

Unfortunately for those of us suffering from central sensitization, it’s the type of pain that doctors and other medical professionals know the least about.

As Dr. Joshi explains, “there are physicians who claim to be pain physicians… who are anesthesiologists… who don’t even understand it.  And they’re teaching at major programs.  It’s scary.”

Central sensitization is as real a type of pain as any of the other three.  And, as Dr. Joshi says, if you’re going to be able to adequately treat pain as a doctor, you better be aware of all four categories.

***

Dr. Joshi also has some really great analogies which help to explain the phenomenon of central sensitization further.  I’ll be elaborating on some of those in my next post.

I hope this was helpful!

Also: you may have noticed that I’ve been playing around with my blog’s format.  I’ve honestly never truly been happy with the appearance of my blog, because I find my options are so limited with premade WordPress themes.  I’m beginning to experiment a little (and even spend a little bit extra!) to try to get things right.  If you have any thoughts or suggestions how improve the appearance of my blog, please let me know!

 

 

 

 

 

What I really want you to know

I never know quite what to call the posts in which I share a video.

Every title I think of sounds either click-baity or boring.  Like for this one: “Mayo Clinic doctor explains central sensitization.”  “Awesome video on central sensitization,” etc. etc.

In this day and age… what do you call something that truly is a “must-watch?”  The term is so overused.

But I really, really want everyone to watch this.

***

Have you ever held something in for so long that, when someone finally validates the way you feel, you end up crying?

That was kind of how it was for me, with this.  This video was so great it actually made me cry.

I know a lot about central sensitization, but, honestly, most of that is from my own research.  (You can check out the articles and researchers I cite in my Resources section, particularly under “Scientific Articles”).

Of course, I’m grateful to have access to these articles, and of course, to the scientists who wrote them.  (Not to mention the education that allows me to understand them– big shout out to my neuroscience professor!).

But when it comes to understanding central sensitization as a scientific concept, there have been many times when I’ve felt pretty alone.

Maybe I shouldn’t feel this way, because, largely, I’ve found the answers I need– my life is so much better since I discovered pain neurophysiology education and the work of Neil Pearson (thank you again, Neil!).

But what I’m talking about is the emotional aftermath of what I went through in all the years before; all the time I spent feeling misunderstood.  All the conflicts and arguments with friends and family over the “weird” symptoms no one could understand… I have sometimes felt very, very alone in trying to articulate exactly what’s happened to me.

***

That’s a big part of why this video blew me out of the water.

Here, Dr. Christopher Sletten, who runs the Pain Rehabilitation Center at the Mayo Clinic in Florida, describes, in patient-friendly language, exactly how central sensitization can happen, and the myriad ways it can affect a person.

***

On my blog, I talk mainly about pain.  That’s been my main symptom, and in some ways it’s the clearest and easiest to write about.

But central sensitization can cause all sorts of bodily sensations to become amplified.

As Dr. Sletten explains, it can make lights seem brighter, and sounds seem louder.  It can make you dizzy.  It can cause digestive upset.

It can really affect all of the sensory input that is meant to help you protect your body and guide you through the world.

And this, of course, will make you look crazy to those who don’t understand.  It can even make you look crazy to yourself.

***

So I love, love, LOVED the part around the 7:20 mark where Dr. Sletten asks, “So how much of this is psychological?  NONE.”  Bam.

“The emotions are a symptom, not a cause.”  YES.

How I wish the people in my life had believed this, all the times I tried to explain it to them ten years ago.

I knew I wasn’t crazy; knew it wasn’t all “in my head.”  But I could never find the right words to convey my reality; to convince people who’d already made up their minds.

It doesn’t mean they didn’t care.  But there’s a difference between knowing you’re cared about, and feeling truly believed and understood.  There’s quite a big difference, actually, and it can hurt to never get that second part from the people you love.  To know they’re tolerating your “craziness,” instead of seeing you for who you really are.

***

I wasn’t really planning on writing such a personal post today.  I seriously LOVE the science behind this stuff, so I was planning to take some notes on important concepts and get more into the nitty-gritty.

But I guess this is the part of my story that I needed to tell today.  More of the nitty gritty will have to come later on.

***

The one sciencey thought I wanted to leave you with right now is that this video provides some great insight into how central sensitization can lead to what are called central sensitivity syndromes.

After all, it’s not just pain.  It’s never just any one thing.  It’s the fact that the sensory information that’s supposed to give your brain cues as to how to respond to your environment is coming in way too “loud.”

This can create all sorts of different symptoms and sensations in different people.  It can lead to chronic pain; some people call it fibromyalgia.  It can cause phantom limb pain; it can cause Complex Regional Pain Syndrome (CRPS).

It can cause lead to diagnoses whose names imply more of a specific focus: chronic pelvic pain.  Temporo-mandibular joint disorder.  Irritable bowel syndrome; other digestive issues.

But they all fall under this umbrella term: central sensitivity syndromes.   Despite having seemingly very different symptoms on the surface, all of these conditions can share a common cause, at the level of the nervous system.

***

So that’s all for now.  I hope you get as much out of this video as I did.  (And if you do, I hope you spread it around– I seriously want everyone in the world to watch it!).

As always, if you have any thoughts or questions for me, you can leave a comment below or email me!
