Post-Exertional Malaise - a discussion including defining and measuring PEM

That is not my experience. When I was mildly affected, I used to exercise and got some postexertional malaise, a lot of it focused on muscles/tendons/ligaments, but I was still able to do sedentary activities as a student. But it wasn't until a relapse and then I became more ill that some symptoms like sore throats and tender lymph nodes became part of my postexertional malaise.

 

Me too regarding PEM and crashes, they are the same severity when I was mild as they are now when I’m mostly bedridden, the only difference is as I’ve gotten more severe they became more frequent, last much longer, and are much less improved by rest. As I got more severe I was in the same crash mode for longer or all the time.

 

Maybe because you were mild in your late teens or early twenties (student) and many of us got ME and had our mild phase much later in life?

Age is a big confounding factor when comparing symptoms and disease course between people, and it’s suggested that younger people experience PEM differently then older.

 

Perhaps. Alternatively, perhaps people don't consider some symptoms postexertional malaise or a certain level of symptoms postexertional malaise in which case it's a bit of bit of a tautology: postexertional malaise always takes the same form and the same severity (whether somebody is mild or severe) only because only a certain set of symptoms and a certain severity of symptoms is seen as postexertional malaise (by a particular individual).

When I had a major relapse, when young, I did get a sore throat and my glands fell swollen, but other times the feeling was less intense.

 

I’ll have to find it from a paper or reference I read, which I cannot remember now. But I also found it intriguing as it said that young pwME describe the experience and symptoms of PEM differently then us adults. If anyone else remembers where I might’ve read that I would appreciate the help.

I should also change its not “well known” to its “suggested” or “described”

 

No it wasn’t Crawley I know the usual suspects and do not read their garbage.

It was from MEpedia page on PEM, which referenced a page from Dr. David Bell on pediatric ME/CFS which referenced a paper from Dr Leonard Jason. It suggested that children do not describe having PEM at all or at least not in the way adults describe it.

For teenagers, which are part of this cohort, they are developed enough to fully describe PEM in the same way as adults if they experience it in the same way, so it’s not much of an extrapolation to say that many teenagers do not experience the symptoms of PEM the same way as adults.

 

Young pwME adopt the language from medical interventions and online sources.

The younger the more likely to assimilate given language into developing verbal and experiential constructs. Your world view is framed by interaction and experience.
You would not recognise ME from descriptions on some websites , it is all " fatigue" focused and descriptions of PEM are shockingly bad . This forms a child's/ adolescent' s reference.

Queries re PEM were up until very recently focused as increase in tiredness and fatigue and other symptoms were not widely acknowledged or ascribed to " anxiety". In many places this is still the case.

If you consider the paediatric literature in UK it's easy to see how young pwME may describe their illness. The language is given to them , if it " fits" then it is not challenged .
Many use fatigue when it is fatiguability.

Placed in context it's not difficult to understand why descriptions differ. If there was better understanding the language may be very different.

I was a tween (11), my mum was an adult, our pem was exactly the same. The only thing to be careful with children is that they very quickly don't know what normal is, because they don't have a long history of life experiences to draw upon.

 

Kids generally don't have the wordage or full comprehension of what words mean.

I had been very fit and healthy child previously then was hit heavily by a lot of brain symptoms. I mainly would use phrases like 'I'm so tired,' which was highly inappropriate to describe things. I had no experience of what it was to be unwell or to describe it to others.

From knowing other child suffers and adult suffers, I've seen no evidence that a child's M.E. differs in any fundamental way.

 

Some do but are limited by the standard vocabulary used.
Some can describe things very well but are not listened to, or their descriptions not drilled down into for appropriate symptom management.
Dizziness, breathlessness and gastric issues have only recently been accepted as signs of paediatric OI issues, and only in some places . Anxiety was the previous catch all and still pertains .

Thanks for re-posting this. I've seen this chart before but I keep forgetting about it.

I do wonder whether I have both "short term" and "long term" PEM? (as defined by this chart)

It's hard enough for me to keep track of even those symptoms that come 1-2 days after "too much" (hard to define) activity. I have no idea how I'd keep track of activity vs. symptoms when these come 7 days (or more) after the activity.

I resist symptom diaries to track PEM because when the few times I've tried it in the past it always led to feeling very depressed over how little I do vs. how many symptoms I get.

I'm impressed by folks who are able track all their symptoms and without it making them feel completely depressed.

 

My PEM is dependent on how much I go over to determine the 'short term' or 'long term' effects.

 

We've discussed this before somewhere. I have two main issues with the chart:

1) What they call immediate PEM is what I'd call fatiguability. (@Trish)

2) The linear presentation makes it look like the 3 stages follow each other. My experience is that

a) I can skip the immediate stage altogether and still get the later stage PEM, and
b) I always get all the symptoms listed under both short-term and long-term PEM together, irrespective of how long a PEM episode lasts.​

 

It can take me several days before PEM becomes an issue.

so PEM is a separate 'disorder'? since when?

 

Unfortunately, PEM has been hi-jacked from the ME community to describe 'malaise' for every illness under the sun.
