Hypnosis and Fibromyalgia

What is fibromyalgia?

Fibromyalgia combines widespread, persistent pain, a fatigue that rest does not repair, unrefreshing sleep, and difficulties with attention and memory that many people describe as a fog. The symptoms fluctuate, they move, and they cannot be seen.

It is recognised by the World Health Organization. In the International Classification of Diseases in force since 1 January 2022, fibromyalgia syndrome appears under MG30.01, chronic widespread pain, itself grouped under chronic primary pain. This deserves to be said plainly, because many people are still told it does not exist.

The diagnosis is clinical, and no test confirms it. The algorithm published by Quebec's Ministry of Health and Social Services says so without hedging: to this day, no laboratory test and no imaging can confirm a diagnosis of fibromyalgia. Tests serve another purpose, ruling out what might resemble it. The Haute Autorité de santé asks for a minimal blood work-up, a blood count, CRP, TSH, CK and liver enzymes, of which the Quebec ministry retains the first four. Both warn against multiplying investigations, which draws people into a spiral of pointless consultations and ends up focusing all their attention on their symptoms.

What "nociplastic pain" means

You will come across this term, and it is worth understanding, because it is also the one most often overstated.

The idea is that there is a third category of pain, alongside pain caused by tissue damage and pain caused by nerve damage. A pain that arises from a change in the way signals are processed, without a visible lesion. The World Health Organization uses this framework in its own definition, and Inserm sees in it what allows fibromyalgia to be described no longer as a medically unexplained syndrome but as a syndrome with nociplastic pain.

And here is the nuance almost nobody writes down. The term is institutionally accepted, but the mechanism is not established. The landmark review on the subject states that this is the term suggested by the international community of pain researchers, and that the mechanisms underlying this type of pain are not entirely understood. The Haute Autorité de santé stays cautious and speaks of functional alterations of the nociceptive system.

In other words: saying that nociplastic pain is the framework accepted today is accurate. Saying that your fibromyalgia is a proven malfunction of your central nervous system that someone knows how to correct goes well beyond what is known. Be wary of any page that explains the mechanism with too much confidence, including one that is selling hypnosis.

A few figures, and the ones that should stop being repeated

• Between 1.5 and 2% of the population according to the Haute Autorité de santé, between 0.7 and 2.1% according to Inserm, 1.5% in Canada in the Canadian Community Health Survey. It is not a rare condition.
• Not nine women to one man. That figure comes from samples of patients already referred to specialist services, where more than 90% are women. Measured without that bias, in the general population, the proportion of women falls to around 59%. The Haute Autorité de santé writes "almost three times more frequent in women". The nine-to-one ratio erases real men, already underdiagnosed because nobody is expecting them.
• The criteria move the figure as much as reality does. Applied to the same population, at the same moment, by the same team, the 1990, 2010 and modified 2010 criteria give 1.7%, 1.2% and 5.4%. The female-to-male ratio itself shifts from 13.7 to 1 down to 2.3 to 1 depending on which set is used. The criteria that serve as the reference today are those of the American College of Rheumatology as revised in 2016.
• The journey is long, longer than the figure that circulates. The most quoted international survey measured 2.3 years and 3.7 different physicians, but that delay starts from the first consultation, and the people surveyed had waited on average almost a year before consulting. The full journey is therefore more than three years. The European recommendations describe high healthcare use for up to ten years prior to diagnosis.

Hypnosis and fibromyalgia: what it aims for, and what it does not do

Let us start with what hypnosis does not do.

It does not cure fibromyalgia, and nothing cures it to this day. It replaces neither your medical follow-up nor adapted physical activity, which remains first-line everywhere. It does not act on the cause, whose mechanisms are not elucidated. And it will not bring your pain down by a percentage announced in advance: nobody can honestly promise that.

What sessions aim for

• Sleep. This is where the signal is least fragile. Inserm's collective expert review, reading the reference meta-analysis, notes that hypnosis on its own still improves sleep disturbance three months after the sessions. Sleep was not, however, one of that study's primary outcomes. It is also, very often, what people come looking for first. See Hypnosis for Sleep and Insomnia.
• A calmer state. The Haute Autorité de santé lists hypnosis among the interventions whose expected effect is relaxation, calm and well-being. It is a modest claim, and it is supported: the same meta-analysis finds a measurable effect on psychological distress. See Hypnosis for Stress and Anxiety.
• Your relationship with pain. The wording is the Haute Autorité de santé's own, and we keep it as it stands: providing resources to learn to change your relationship with pain and how you cope with it. That is not the same thing as lowering pain, and the distinction is the whole subject. See Hypnosis for Pain Management.
• Daily self-hypnosis. This is explicitly what the Haute Autorité de santé singles out: self-hypnosis practised independently once it has been learned. On this subject, what you do between sessions counts for more than the sessions themselves.
• Living with a condition that lasts. The unpredictability, the things given up, the guilt of letting people down. See Hypnosis for Chronic Illness and Hypnosis for Dealing with Uncertainty.

What the research says, without arrangement

We have to be direct, and this section will tell you things most pages on this subject leave out.

The 2017 European recommendations examined hypnotherapy by name, and issued an unfavourable evaluation. The exact wording is "weak against", with 86% agreement among the panel. Guided imagery, often confused with hypnosis, is graded more severely still, "strong against", alongside homeopathy. Two points matter. First, those same recommendations define a weak evaluation as one that a substantial minority of informed people would not endorse: it is not a rejection. Second, their literature review stopped in May 2015, and rests on a single meta-analysis, the one published in 2011.

The most complete meta-analysis came later, and is more favourable. Published in 2017, it brings together seven randomised trials and 387 people. It finds that 18 more people out of 100 reach at least a 50% reduction in pain, with an interval running from 2 to 35, and a measurable effect on psychological distress. Its authors conclude with a well-chosen word: hypnosis and guided imagery hold promise, within multicomponent management. Hold promise, not demonstrated. Two reservations we will not hide: the earlier meta-analysis acknowledged that its effect on pain was associated with low methodological quality and with low quality in the interventions themselves, and none of these studies measured safety.

The French and European sources do not say the same thing, and that needs naming. Inserm's collective expert review, in 2020, writes in its recommendations that the efficacy of hypnosis in supporting people with fibromyalgia is established. That is the sentence competing sites quote. It is almost always quoted without its second half: in its own evidence chapter, the same report states that these results are not robust enough given the significant methodological biases found in the included studies. The same document, a few pages apart.

The most recent position is that of the Haute Autorité de santé, in June 2025, and it is the one we follow. It writes that hypnosis may be considered in fibromyalgia, given its value in other chronic pain conditions and the use of self-hypnosis independently once learned. The important word is "other": the justification does not come from fibromyalgia data. It attaches conditions to that opinion, including stopping if there is no response, and one precaution we have made our own, set out just below.

Something we owe you plainly. That recommendation specifies that hypnosis should be delivered by a health professional or a psychologist trained in the approach. That is the French setting, where hypnosis is largely practised in hospitals. In Quebec the framework is different: hypnosis is not a reserved activity, psychotherapy is, and we do not practise it. We would rather set out that difference than pass over it in silence, and let you judge.

What this means in practice. We do not claim to do better than adapted physical activity, which remains first-line. Nor do we claim that hypnosis is demonstrated in fibromyalgia. We work on sleep, on calm and on your relationship with pain, alongside your medical follow-up, and that is exactly the scope the guidelines recognise.

How a session works on this subject

The interview. How long, how the diagnosis was made and by whom, what follow-up is in place, and what has already been tried. Then what costs you the most today, what you have stopped doing, and what your nights look like. If you have no diagnosis, or if your doctor does not know about this step, we will ask you to go back to them before we undertake anything. This is not a formality: the Haute Autorité de santé explicitly asks that the doctor following you give an opinion before hypnosis begins.

The objective. Agreed together, and never "make the pain disappear". Rather: get back to sleep after the four o'clock waking, or get through a bad day without it taking the whole week with it.

The induction. A natural state of focused attention that you already know without naming it. You stay conscious, you hear everything, and you can speak or stop whenever you wish. You will not be asked to hold any uncomfortable position.

The work. It most often concerns sleep, calm, the way you speak to your body when it does not keep up, and the things you have given up. Some people also work on perception itself, through images of distance or temperature, without that being a promise.

The debrief and the exercise. A conversation about what you experienced, and a self-hypnosis exercise to take away, short, designed to be practised daily and usable on bad days. That is the part that counts most. Some practitioners provide it as a recording.

And a rule we apply. The Haute Autorité de santé asks that sessions stop if there is no response. We follow it: if nothing moves, we will tell you rather than offer you one more session.

Sessions work in person as well as by video, which matters on the days when getting out of the house is beyond you. The number of sessions is agreed at the first meeting.
