What supplements are actually worth it for fibromyalgia, honestly?▾
None of them clear our grade B bar. Magnesium is grade C: a plausible mechanism around muscle and nerve excitability, but only small, underpowered trials. Vitamin D is grade C and only helps people who are genuinely deficient, correcting a real deficiency is the supportable action, not supplementing above normal levels. CoQ10 is grade C: several small positive trials, no large confirmatory trial. The honest verdict: cheap, low risk, worth discussing with your doctor, but do not expect much, and do not spend real money expecting a result. This carries no product recommendation.
What is the best thing for fibromyalgia pain that is not an opioid?▾
Three drugs are FDA-approved specifically for fibromyalgia: pregabalin (2007), duloxetine (2008), and milnacipran (2009), grade B, resting on the approval basis plus randomized trials. Amitriptyline is guideline-recommended and widely used off-label, but it is not FDA-approved for fibromyalgia, and the 2015 Cochrane review (Moore et al.) found no first- or second-tier evidence for it and rated the supporting trials very low quality, so treat it as grade C and mixed, the same honest split this page already gives low-dose naltrexone. Non-drug: pacing, already the highest-value step on this page. Every drug named here is a conversation with your clinician, never a self-start.
Is fibromyalgia a real medical condition, or is it all in my head?▾
Fibromyalgia is real, and it is not in your head. It is a real, recognized disorder of how the nervous system processes pain, not a psychiatric condition and not a diagnosis of exclusion. The best-supported mechanism is central sensitization: the brain and spinal cord amplify pain signals. This is measurable with quantitative sensory testing, which consistently finds people with fibromyalgia are more sensitive to standardized pressure and heat than controls, grade B, a well-replicated finding across many independent studies. Brain imaging adds supporting but less settled evidence: a systematic review of structural and functional MRI studies (Cagnie et al., Seminars in Arthritis and Rheumatism, 2014) found moderate evidence of reduced grey matter in pain-processing regions like the anterior cingulate cortex, grade C, real but heterogeneous across studies and not a diagnostic scan. A subset of patients also show small-fiber neuropathy on skin biopsy, roughly 40 to 50 percent in pooled estimates (Oaklander et al., Pain, 2013; meta-analysis PMID 30314675), grade C, a real physical finding in a meaningful minority but not present in everyone and not required for diagnosis. Institutionally, fibromyalgia is formally recognized by the American College of Rheumatology, has its own World Health Organization ICD-11 code (MG30.01, chronic widespread pain), and has dedicated management guidelines from EULAR (2017) and NICE (NG193, 2021). None of that adds up to a cure, and no scan or blood test can diagnose it today, but the pain is physiologically real and it has a name every major medical body recognizes.
What are the actual diagnostic criteria for fibromyalgia? Has my doctor been using outdated ones?▾
The old 1990 American College of Rheumatology criteria (Wolfe et al., Arthritis and Rheumatism, 1990) required a doctor to press on 18 specific points and find tenderness in at least 11 of them. That exam was retired years ago. The current standard is the 2016 revision (Wolfe et al., Seminars in Arthritis and Rheumatism, 2016) of the 2010/2011 criteria, and it does not use tender-point pressing at all. It uses two scored scales: the Widespread Pain Index (WPI, 0 to 19, counting painful body areas) and the Symptom Severity Scale (SSS, 0 to 12, scoring fatigue, unrefreshing sleep, cognitive symptoms and other complaints). Criteria are met with WPI 7 or higher and SSS 5 or higher, or WPI 4 to 6 with SSS 9 or higher, plus generalized pain in at least 4 of 5 body regions, with symptoms present at a similar level for at least 3 months. One line matters most for a dismissive visit: the criteria state outright that a fibromyalgia diagnosis is valid irrespective of other diagnoses, and does not exclude the presence of other clinically important illness. It is not a last-resort label for when nothing else is found, and it can coexist with other conditions. A doctor is not applying the current standard if they are still pressing on 18 points or treating it as a diagnosis that only counts once everything else is ruled out. Meeting these numbers is not a diagnosis: only a clinician can diagnose fibromyalgia, using this criteria alongside your full clinical picture.
My doctor does not believe I have fibromyalgia, or dismisses it. What can I actually do?▾
Bring the criteria, not just your symptoms: ask specifically whether your pain and symptom pattern meet the 2016 ACR criteria (WPI and SSS scored, generalized pain in at least 4 of 5 regions, present at a similar level for 3 or more months), and ask whether the outdated 18-point tender-point exam is being used instead. A reasonable workup rules out other explanations for widespread pain, commonly thyroid function, inflammatory markers (ESR and CRP), and vitamin D, not to disprove your pain but to check for a treatable overlapping condition, since a fibromyalgia diagnosis does not exclude having something else too. If a clinician will not apply a named, published diagnostic standard to a real symptom pattern, asking for a rheumatology referral or a second opinion is a reasonable next step, not an overreaction. This is informational only, not a diagnosis; only a clinician can diagnose fibromyalgia.
Is my fibromyalgia actually long COVID or ME/CFS? How do you tell them apart?▾
The thing that tells them apart is not your pain, it is what exertion does to you afterwards. The three labels are gated on three different things. ME/CFS is gated on post-exertional malaise: under the 2015 Institute of Medicine criteria (the standard the CDC uses) a person needs a substantial, lasting drop in what they could do before, plus unrefreshing sleep, plus post-exertional malaise, meaning physical, mental or emotional exertion that reliably makes symptoms worse starting hours to about a day later. PEM is mandatory there, not optional. Fibromyalgia is gated on pain: its 2016 American College of Rheumatology criteria turn on generalized pain across the body and how severe the symptom burden is, present at a similar level for at least three months. Post-exertional malaise is not one of its requirements. Long COVID is gated on neither symptom, it is gated on onset: it is an umbrella term for symptoms that begin after a confirmed or probable SARS-CoV-2 infection and persist, at least two months in the World Health Organization's 2021 case definition, twelve weeks or more for what UK NICE guidance NG188 calls post-COVID-19 syndrome. It is a category defined by what started it, not a single illness. So these are not three competing answers to one question. They answer three different questions: what does your pain look like, what does exertion do to you, and what set this off. More than one can be true of the same person at the same time, which is exactly why a fibromyalgia diagnosis does not rule out either of the other two. Grade A on this: it comes straight from the criteria documents, not from an estimate. Only a clinician can diagnose any of these three, so this is what to understand before an appointment, never a way to relabel yourself.
Can long COVID turn into ME/CFS or fibromyalgia? How often do these three actually overlap?▾
Often enough that it is a normal question. The honest caveat first: the published numbers come from specialist clinics and self-selected surveys, not from the general population, so read them as a signal about how common the overlap is, not as your personal odds. In a Northern California post-COVID clinic, 43 percent of the patients whose symptoms had persisted beyond six months met full ME/CFS criteria, 45 of 105, from 134 patients analysed in total (Bonilla et al., Frontiers in Neurology, 2023, PMID 36908615). A German prospective cohort found about 45 percent (19 of 42) met the Canadian Consensus Criteria for ME/CFS, though that group had already been selected for persistent moderate to severe fatigue and exertion intolerance at six months, so it is an overlap rate inside an already-symptomatic subgroup rather than among all long-COVID patients (Kedor et al., Nature Communications, 2022, volume 13, article 5104). A web survey of 616 people about six months after a COVID diagnosis found roughly 30 percent screened positive for fibromyalgia on modified 2011 ACR criteria, which is self-report rather than a clinical exam (Ursini et al., RMD Open, 2021). Grade C on all three: real peer-reviewed studies, all in referral or self-selected groups, none population-representative. Running the other direction, in the largest and most recent dataset, 45.0 percent of people who met ME/CFS criteria also met fibromyalgia criteria, and 76.1 percent had at least one chronic overlapping pain condition against 17.4 percent of healthy controls (Fall et al., BMC Neurology, 2024, PMID 39425035, 595 patients and 328 controls across seven US specialty clinics, 2012 to 2020). Grade C, still specialty-clinic recruited and cross-sectional. None of this says the three conditions are the same thing. It says the labels describe overlapping, not identical, symptom clusters, and a meaningful share of people in any one bucket would also qualify for another. It also does not tell you which of them you have: meeting criteria on paper is not a diagnosis, and only a clinician can make one.
What is the single question to bring to my appointment, and is there a checklist for it?▾
The post-exertional malaise question, and both halves of it matter. First: after physical, mental or emotional exertion, do your symptoms reliably get worse starting hours to about a day later, rather than immediately? Second: when that happens, does it last more than 24 hours? Yes to both is the strongest single pointer toward ME/CFS, or toward a PEM-driven long COVID presentation, rather than fibromyalgia on its own. Ordinary tiredness right after activity, and pain that flares during activity and settles the same day, are a different pattern. There is a real instrument for this, and the caveat comes before the name: it is a screening aid to bring to an appointment, never a self-diagnosis, and only a clinician can diagnose. The DePaul Symptom Questionnaire post-exertional malaise items (DSQ-PEM) cover how often PEM happens, how severe it is, how long it lasts, and whether you avoid exercise because it makes you worse. Five of those are the items the NIH and CDC Common Data Elements set recommends for ME/CFS research, and the paper that validated them adds five more on duration and recovery (Cotler et al., Diagnostics, 2018, PMID 30208578). Grade B: validated as a screening and research instrument, which is not the same as proving a diagnosis for one person. Use it the way it is meant to be used, which is to fill it out before your appointment so you can describe the pattern precisely instead of reconstructing it under pressure. It does not produce a diagnosis and it is not a score to act on by yourself. Only a clinician can diagnose.
