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...
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.
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.
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.
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.
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!

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.
| |

|
Noticeable when concentrating on something else.
|
Nausea, headache, appetite loss.
|
7
|

|
Interferes with concentration.
|
Drop things, grip unreliable.
|
8
|

|
Difficult to think about anything else.
|
Trouble picking things up.
|
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.
| |
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.

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

|
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.

|
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.
