Pain rating scales must describe reality, or they are meaningless

The value of valid reporting in medicine is so fundamental there's no question about it when the issue is explicity raised. Unfortunately, it's implicitly absent in too many aspects of CRPS care.

The inspiration for this article came from paperwork requiring me to rate my pain on the standard 1-10 scale. This is so irrelevant to life now that it's simply not approachable.

 
Between my self-care strategies and spectacular mental gymnastics, the level of what most people would experience as "pain" is a secret even from me, until it's strong enough to blast through the equivalent of 14 steel doors, each three inches thick. At that point, the numeric level is off the charts.

 
What's useful and relevant is how well I can cope with the backpressure caused by the pain reflexes and the central and peripheral nervous system disruption this disease causes.

 
Read on without fear, because for one thing, it's not contagious, and for another, your experience of pain -- whether you have CRPS or not -- is uniquely your own. This is mine, as it has changed over the years...

 

Step 1: Acute CRPS, with otherwise normal responses

My first pain rating scale, just a few years into the disease's progress, was suitable for a normal person's experience. My experience of pain was still pretty normal (apart from the fact that it didn't know when to stop):

Mental impact
Physical changes
0
No pain at all.
1
Hurts when I stop and look.
3
3
Neither looking for it nor distracted.
5
5
Noticeable when concentrating on something else.
Nausea, headache, appetite loss.
7
7
Interferes with concentration.
Drop things, grip unreliable.
8
8
Difficult to think about anything else.
Trouble picking things up.
9
9
Makes concentration impossible.
Interferes with breathing pattern. No grip.
10
Can’t think, can’t speak, can’t draw full breath, tears start – or any 3 of these 4.
Unrated even numbersindicate a worse level of pain than prior odd number, which does not yet meet the criteria of the following odd number.
Note that weakness is only loosely related to pain. I drop things and have trouble picking things up at times when I have little or no pain. However, as pain worsens, physical function consistently deteriorates.

Notice how the scale ties the rating numerals to physical and mental function. This is crucial, for two reasons -- one personal and one pragmatic:

 
- Personally, I can't bear to let misery get the better of me for long. Tying the numbers to specific features keeps the awful emotional experience of pain from overwhelming me. Making the numbers practical makes the pain less dramatic.

- Pragmatically, in the US, health care is funded by a complex system of insurance. Insurance companies are profit-driven entities who are motivated not to pay. They don't pay for pain as such, only for limits on function. This makes my pain scales excellent documentation to support getting care paid for, because MY numbers are tied to explicit levels of function.
 

Step 2: Early chronic CRPS, with altered responses

My next was upwardly adjusted to describe learning to live with a higher level of baseline pain and noticeable alterations in appearance and ability:

Mental impact
Physical changes
3
3
Neither looking for it nor distracted. Forget new names & faces instantly.
Cool to touch @ main points (RCN both, dorsal R wrist, ventral L wrist). Hyperesthesia noticeable. .
5
5
Interferes with concentration. Anxiety levels rise. Can't retain new info. Can't follow directions past step 4. May forget known names.
Nausea, headache, appetite loss. Grip unreliable. Hyperesthesia pronounced. Color changes noticeable.
7
7
Absent-minded. White haze in vision. Can't build much on existing info. Can follow 1 step, maybe 2. May forget friends' names.
Drop things. Cold to touch, often clammy. Arms & palms hurt to touch.
8
8
Speech slows. No focus. Behavior off-key. Can't follow step 1 without prompting.
Can't pick things up; use two hands for glass/bottle of water.
9
9
Makes concentration impossible. Hard to perceive and respond to outer world.
Interferes with breathing pattern. No grip. Everything hurts.
10
Can’t think, can’t speak, can't stand up, can’t draw full breath, tears start – or any 3 of these.

Notice how specific I am about what general tasks I can complete -- following instructions, lifting things. These are the fundamental tasks of life, and how do-able they are is a fairly precise description of practical impairments.

Clinical note: tracking functional impairments is key to getting compensated for delivering appropriate care.
 

Step 3: Established chronic CRPS

And my third scale changed to describe living with more widespread pain, a higher level of disability, and -- most tellingly -- a physical experience of life that's definitely no longer normal:

Mental impact
Physical changes
3
3
Neither looking for it nor distracted. Forget new names & faces instantly.
Cool to touch @ main points (RCN both, dorsal R wrist, ventral L wrist, lower outer L leg/ankle, R foot, B toes). Hyper/hypoesthesia. Swelling.
5
5
Interferes with concentration. Anxiety levels rise. Can't retain new info. Can't follow directions past step 4. May forget known names.
Nausea, headache, appetite loss. Grip unreliable. Hyper/hypoesthesia & swelling pronounced. Color changes. Must move L leg.
7
7
Absent-minded. White haze in vision. Can't build on existing info. Can follow 1 step, maybe 2. May forget friends' names.
Drop things. Knees buckle on steps or uphill. Cold to touch, often clammy. Shoulders, arms & hands, most of back, L hip and leg, B feet, all hurt to touch. L foot, B toes dark.
8
8
Speech slows. No focus. Behavior off-key. Can't follow step 1 without prompting.
Can't pick things up; use two hands for glass/bottle of water. No stairs.
9
9
Makes concentration impossible. Hard to perceive and respond to outer world.
Interferes with breathing pattern. No grip. No standing. Everything hurts.
10
Can’t think, can’t speak, can't stand up, can’t draw full breath, tears start – or any 3 of these.

 

The CRPS Grading Scale

This case has evolved considerably in the past year. The other scales measure the wrong things now. Asking me about my pain level is bogus. It would have the asker in a fetal position, mindless; is that a 7 or a 10? Does it matter?

 
I need to avoid thinking about depressing things like my pain and my disability, because I must function as well as possible, every minute of every day. I focus relentlessly on coping with these issues and squeeezing as much of life into the cracks as possible -- on functioning beyond or in spite of these limitations.

 
The fourth rating scale is much simpler than its predecessors. It's based, not on level of pain or disability, but on the degree to which I can compensate for the disability and cope past the pain. Therefore, this rating scale remains meaningful, because it describes my actual experience of life.

Mental impact
Physical changes
A. Coping gracefully
(baseline)
Track to completion, baseline memory aids sufficient, comprehend primary science, think laterally, mood is managed, manner friendly.
Relatively good strength and stamina, able to grasp and carry reliably, knees and hips act normal, nausea absent to minimal, pulse mostly regular.
B. Coping roughly
B
Completion unrealistic, extra memory aids required and still don't do it all, comprehend simple directions (to 3-4 steps), think simply with self-care as central concern, unstable mood, manner from prim to edgy to irritable.
Moderate strength and stamina, grip unreliable and muscles weaker, balance goes in and out, knees and hips unreliable, nausea and blood sugar instability alter type and frequency of intake, occasional multifocal PVCs (wrong heartbeats) and mild chest discomfort.
C. Not coping well
C
Hear constant screaming in my head, see white haze over everything, likely to forget what was just said, focus on getting through each moment until level improves, manner from absorbed to flat to strange, will snap if pushed.
Muscle-flops, poor fine and gross motor coordination, major joints react stiffly and awkwardly, restless because it's hard to get comfortable, unstable blood sugar requires eating q2h, bouts of irregularly irregular heartbeat.
D. Nonfuntional
D
Unable to process interactions with others, suicidal ideation.
Unable either to rest or be active. No position is bearable for long.



There is no Grade F. Did you notice that? As long as I have a pulse, there is no F. This is rightly called "the suicide disease", so the meaning of F is obvious.

In the words of the unquenchable Barrie Rosen,
"Suicide is failure. Everything else is just tactics."

So what's the point of all this?


Documenting patient experience in terms that are meaningful and appropriate advances the science.

The treatment for this disease is stuck in the last century in many ways, but that's partly because it's so hard to make sense of it. The better we track real experience with it, the better we can make sense of it.

 
Since studies, and the funding for them, come from those who don't have the disease, this is the least -- and yet most important -- thing that patients and clinicians can do to improve the situation for ourselves and those who come after us.
 

This isn't a bad snapshot of the natural history of my case, either. Understanding the natural history of a disease is a key element of understanding the disease.

Imagine if all CRPS patients kept meaningful, evolving pain rating scales, and pooled them over the years. What a bitingly clear picture would emerge!

New type of nerve cell in brain. POTSers, take note... and hope

This article discusses the discovery of a new type of neuron in the hypothalamus. 

A new type of nerve cell found in the brain

This specific type of nerve cell handles cardiovascular functions, playing some sort of role in regulating heart rate and blood pressure. The cardiovascular system being the interlocked system  that it is, this presumably also includes force of heart contractions, tension of the vessels, and other autonomically-driven activities.

The autonomic part of the nervous system is supposed to be the ring-master for the automatic functions of life, everything that has an up and a down: blood pressure, heart rate, sleeping/waking, appetite and thirst, and so on. Its dysregulation in CRPS is probably one of the most stubborn problems in treating and managing this disease. Finding a type of nerve that so explicitly  handles one part of that extraordinarily complex set of inter-relating functions is fascinating enough, but the ramifications are tremendous.

Here they discuss it in terms of its relationship to the thyroid, an endocrine organ that's an important part of those regulatory mechanisms, on the chemical-messenger side. The thyroid drives the creation and balance of these types of nerves; these types of nerves then influence the output of the thyroid. It's a metabolic two-step, a mutual relationship characteristic of nearly every chemical/physical connection in the human body.

Those who have POTS and other forms of autonomically-driven cardiovascular problems might have a new cause for hope. Being able to separate out that particular set of mechanisms from the rest of the nervous system, at least to some degree, may give them a chance of managing their disease better without throwing the rest of their autonomic functions further off.

Anyone who has been that nauseously dizzy and that weak for that long would be terribly glad of the chance. This is great science, and not just for those with thyroid disorders.

Pain is a pity, but really ...

I got a remarkably thoughtless comment from someone on the physician-driven site, crpsnews.org:
"Everyday is certainly a struggle for people with CRPS because they live in pain 24/7. While there is no cure for the disease, it can be slowed and likely to go into remission if treated early, ideally within three months of the first symptoms."
This remark was so fatuous and misguided that I found it alienating, but it raised several important issues that do come up -- especially in regard to people who mean well but don't know much about it (regardless of their educational level.)

Here are the main points of that remark:

1. Pain is why people with CRPS are to be pitied.
2. It's incurable, so don't go there.
3. It can be slowed or pushed into remission...
4. If you catch it really early.

Those of you who've followed me, know what's going through my head right now... "Where do I even start?"

Not with # 1. We'll have to come back to # 1. Let's go in reverse order.

4. "Diagnose it early, ideally within 3 months of first symptoms." Physicians control diagnosis; patients can only control how they respond to it. Since most cases of CRPS aren't even diagnosed for YEARS, that's not a useful remark. Say it at every medical workshop you go to; leave it out of a patient-driven site, because it's a slap in the face.

3. The remark on remission is slighly confusing.  Remission in CRPS is not like remission in cancer. It's a fragile state which can revert at any moment over the slightest thing. It's nothing like a cure. Remission is still possible years on, as the anecdotal evidence indicates.

2. A cure, as they pointed out, doesn't exist -- yet. And, with the wrong clinical focus and a hopeless clinical attitude towards a cure, it's no bloody wonder.

It can be cheaply prevented in ~80% of cases by 500 mg vitamin C, 3 times daily, for 2 weeks before and 3 months after surgery (or 3 months post-injury.) That's much more realistic than CRPS getting diagnosed within months, but so few people know about it that it doesn't happen much.

Result: lots of needless CRPS.

Spread the word about 500 mg vitamin C. It could save lives.
Most people who don't have CRPS focus on the pain as the reason for sympathy. Everybody has had pain, and the idea of pain is what they think they can identify with...
The pain of CRPS is like nothing else I ever experienced before. Yet I was an emergency nurse, motorcyclist, weightlifter, runner, horse rider, gymnast, martial artist... and a statistic, having endured more than one attempt on my life. (I've had an eventful life.) Plenty of opportunities to hurt; always recovered fast.


Yet, despite the often show-stopping pain I now live with, PAIN IS THE LEAST OF MY PROBLEMS. It's the weakness, autonomia, and cognitive decline that are the real problems.

That's where the research needs to be.

That's where the help is needed.

That, honestly, is where the most empathetic and useful sympathy lies :-)

Imagine feeling your ability to think, learn and remember simply dissolving, and there is nothing at all that you can do about it. You can hope it will come back to some degree, and eventually it does (if you avoid everything you're now sensitive or allergic to, eat tons of antioxidants and greens, drink lots of water, and don't screw up anything about your life at all -- while you can't remember what just happened, let alone all that you have to do...) but you know there are no guarantees, and after awhile, the repeated gapping starts to add up.

For a brain, that sucks, eh?

Doesn't that seem a bit more distressing than physical pain? I think so. It certainly has more of an effect on what I can do with my life.

Pain can be pushed through; the weakness, autonomia and cognitive decline are virtually impossible to push through.

Why is that? Because I need my muscles to be able to recover in order to rebuild melting muscles, my autonomic nervous system (ANS) needs to work well enough to let me regain control of my ANS, and I need my brain to work out how to help my brain.

It's like opening a box with the crowbar inside.

Relentless attention to activity, food and supplements, and state of mind are mandatory for a bearable life -- not because of the pain, but because of the weakness, autonomia and gradual brain-death. In order to barely stand my ground, I have to dance as fast as I can.

That's very hard for most people to wrap their heads around. It seems too hard. But to those of us with chronic CRPS, it's just another day. We have to manage all that and still somehow keep food in the house, laundry done, bills paid... relationships intact.


This focus on pain, to the exclusion of the more thoroughly disabling issues, has led to a serious misapplication of resources. A lot of lives have been damaged or destroyed because of that willful blindness in the medical and treatment domains. So it frustrates me, especially as a passing remark dispensed from a physician-driven site. (I wonder where their funding comes from... )

Sympathy is a lovely instinct, it really is, and I sure don't want to discourage it. Though I don't see sympathy in the remark I quoted above, I have heard people without CRPS express genuine sympathy in nearly identical terms. And they really do mean well. That matters!

There's a lot to be said for being sympathetic to someone's actual problems, which may not be exactly what you might expect. This would lead to more understanding, better connections to those who have it, more effective help, and in the end, to more effective care.

...

This morning, I woke up from a dream where I was running an international conference on CRPS, where 3/4 of the presentations were given by non-physicians: expert patients, massage therapists, PTs, acupuncturists -- you know, the people who really know about CRPS, and the stuff that really works for the real problems it causes.

In this dream, doctors could get a lot of CEUs, but they had to spend 60% of their time in non-physician workshops to get them. (How did I come up with 60%?) There was, how shall I put it, a certain amount of fussing about that...

It was a weird dream. Who knows, though, it could happen... It might do people like that staffer at crpsnews.org a world of good.
