Fibromyalgia Diagnosis Classical Definition:
Pros And Cons

The classical definition of fibromyalgia diagnosis as defined in 1990 by the American College of Rheumatology makes a number of statements that are important:

. Muscle Pain duration of more than three months

. Muscle Pain above and below the belt on both sides

. Eleven out of eighteen typical muscle points being painful (not just tender)



Those are the 18 groups of sore muscle points in the classical definition of fibromyalgia

They have little relation to reality for fibromyalgia diagnosis!

This fibromyalgia definition is remarkable by:

- its desire to define fibromyalgia as a chronic pain

- its desire to define fibromyalgia as a “full” picture

- its desire to define fibromyalgia as an extensive disease

The chronicity of the pain, i.e. after many months, makes it more difficult to treat. By the time a sufferer has developped all those tender points fibromyalgia pain has reached chronicity a number of secondary effects have developed:

- the receptors involved with the memory of pain are activated and neuropathic characters are present

- anxiety and depression are often present

- pain is worse because of recruitment (a nervous system phenomenon where neurons normally not involved in the pain are "recruited" and participate in the pain making it worse)

- the characters of fibromyalgia pain make it more difficult to comprehend to the patient, to the family and even to the doctors and suspicions are developing attracting remarks such as “its all in your head”, “you must get hold of yourself”, “hysteria”, “somaticisation”, “hypochondriac”

- moreover, fourteen of the eighteen points are postural muscles. As such they are covering many fibromyalgia trigger points but this is for a specific reason that are discussed in another chapter.

Its desire to define fibromyalgia as a fuller picture ignores the fact that it never develops as such overnight, out of the blue! All slowly developing fibromyalgia symptoms are ignored for quite a while.

Its desire to define fibromyalgia as an extensive disease leaves a great number of patients in limbo about what they are suffering from as they start having pain on one side for quite a while before slowly and surreptitiously extending to the other side.

Even if fibromyalgia develops slowly and is not that obvious to start with, it may have more clues to what is happening and those clues are ignored at the patient’s expense.

What are those clues? They are all the other signs and symptoms that are frequently encountered in fibromyalgia.

Fatigue develops rapidly and its association with muscle pain is highly suggestive. I do not think I would talk about fibromyalgia with muscle pain or fatigue alone without the other.

Are they enough? Probably not. They may be enough together but the probability of fibromyalgia is increased if other signs are also present.


I prefer to give the fibromyalgia sufferer three tools:

- make the patient draw all the pains that they suffer from at one time or another. Drawing is easier than describing and it is often very suggestive

- give a list of all possible symptoms and find out if they exist. I still have to meet a patient with all symptoms

- give the patient a probability of having fibromyalgia. This is a new tool and is not yet defined with precision.

Probability of having a symptom in a diagnosed fibromyalgia has been done but it will always be difficult to ascertain it with precision given the absence of a specific biological marker at present.

The history is more important than the examination. Examination has two targets:

- find painful points that may be suggestive of other deficits (such as hypovitaminosis D) or of other diseases.

- define those points that may be helped by direct injection when this type of treatment is required.

Otherwise, it is totally useless. Even when one considers that a very sensitive skin point may overlay a muscle point. How to distinguish the two? Say that the point is not a real one because pain occurs before the four kilograms pressure at which the muscle point should be defined? This is a waste of time when so many other clues are present and defining.

Fibromyalgia diagnosis rests mainly on the history and description by the fibromyalgia sufferer. What's important is to make sure that other frequently associated disease are not overlooked and that effective treatment for fibromyalgia patients is started early!

Fibromyalgia diagnosis should be an early one so fibromyalgia treatment is successful. This is a condition to avoid entry into chronicity.

The clues are there for those who listen.

Fibromyalgia diagnosis is based on balance of probabilities using all the fibromyalgia symptoms.

Fibromyalgia diagnosis is enhanced by the presence of triggers, co-morbidities or family history.

The diagnosis is helped by the use of tools to better understand the suffering.




Understanding fibromyalgia is the first step towards relief.
