CRPS, or Complex Regional Pain Syndrome (Type 1), is a change in the nervous system that's usually triggered by a very painful episode. The bad kinds affect the brain, nerves, muscles, skin, metabolism, circulation, and fight-or-flight response. Lucky me; that's what I've got. ... But life is still inherently good (or I don't know when to quit; either way) and, good or not, life still goes on.

Pain rating scales that describe reality

I'm filling out paperwork for these assessments. It's a lot of homework, especially since they didn't provide anything I could edit in softcopy. (Wait... how long have computers and the internet been around? Doesn't the ADA require hospitals to provide access? ... ok, never mind. Anyway.)

 
I got to the usual 1-10 pain rating scale and my gorge rose. That's so irrelevant to my life now that I can't even throw a dart at it.

 
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.

 
You can 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 numbers indicate 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 practical:

 
- 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.

- Practically, 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. (Hah! Wiggle out of that, you bottom-feeders.)

 

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 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.
 

Step 3: Established chronic CRPS

And my third 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

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 5 or a 10? Does it matter?

 
I need to avoid thinking about depressing things like my pain and my disability. I focus pretty relentlessly on coping with them 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, which stands for Failure.

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

So what's the point of all this?

Documenting our own 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 our experience with it, the better outsiders 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 we 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 we all kept pain rating scales, and pooled them over the years. What a bitingly clear picture would emerge.

 
I've never sat back and looked at all of these pain rating scales together. It's certainly an interesting mental journey.

  1. Excellent post! Much more useful than the simple 0 - 10 scales that don't take into account our ability to learn to cope w/ chronic pain.

  2. You continue to amaze me. I hope that someone who makes decisions that affect your life gets to read this post--and that they do the right thing to ease your life. I also hope this rating scale gets published so that other people in pain can create a more useful scale for their situation.

  3. This is absolutely superb! Words cannot suffice. This is an ideal tool to more coherently understand and assess the levels of pain that patients are in through the impact it has on their lives physically, mentally and neurologically.

    I've have previously tried to use the 1-10 pain scale descriptors as a base to describe my own non-pain symptoms (dysautonomic issues as a result of the CRPS) and it helped to put it into context amazingly which resulted in appropriately pro-active discussion about how to proceed. But they were not perfect, and I would have liked to have created something 'better'. These scales you have created fit the bill perfectly.

    I am particularly pleased that your timeline of scales shows clearly how your concept of a pain scale has changed over time as your condition, symptoms, baseline and coping skills have developed. In the very early days a low score was pretty darn good, whereas these days a low score relates to somewhat less pain and mental disruption than usual. It is clear that one pain scale does not fit all, and that one pain scale does not always fit one patient over time, either.

    The concept of creating a personal scale to describe symptoms re functionality and life experience is totally appropriate to better understand a patient's experience and limitations regarding their pain.

    From a historical personal experience, my concept of what the 1-10 pain scale *meant* changed during the time I was a pain physio' patient for the first time (pre-diagnosis, so we didn't know the severity of what we were dealing with). My pre-physio' score was low because I assumed the higher numbers were for other people who'd lost limbs in warfare and such like. During the physio programme I found that my coping skills were far better than other patients, so my end-of-physio score was even lower as I took myself further down the scale for knowing I coped better than others. Problem: That my pain had not reduced at all, but that the scores in my medical notes clearly suggested that it had. Any professional or patient knows that a number is a number within each individual's understanding of the scale. The trick is figuring out what we can use instead.

    Your answer is perfect: stop trying to create a scale that fits all and help patients to create scales that are personal to their daily experience and far far clearer for medical practitioners to work with.

    Super work, Isy Aweigh. This really is a set of excellent templates.

  4. Filling in the text with functional changes that describe your own reality is a simple thing to do. I take a copy to my providers and ask them to keep it in my chart. They absolutely love it (the bright ones do, anyway) because it DOES give the numbers meaning and it DOES give them ammunition to fight for my care.
