If a Parent Has Fibromyalgia, Will Their Child Get It?

Not necessarily. Fibromyalgia can run in families, so having a parent with it increases your risk. But it has no simple inheritance pattern, and a parent's diagnosis cannot tell you whether you will develop it. MedlinePlus Genetics explains the distinction.

Perhaps you've watched your mother rearrange her day around pain. Now, when you wake up aching, you wonder whether you're seeing the beginning of something familiar. Or perhaps you're the parent, worrying about what your diagnosis might mean for your child.

You deserve an answer that takes that worry seriously without making promises the research cannot support.

Family history is useful information. It isn't a diagnosis, and it isn't a reason to blame yourself for having children.

How fibromyalgia runs in families

Fibromyalgia has a genetic component, but researchers have not identified a single gene that determines whether someone will develop it. Many genetic differences can contribute, alongside other influences on health. The condition does not follow a straightforward parent-to-child inheritance rule.

The National Library of Medicine's genetics guide describes both genetic and environmental contributions. Family members share more than DNA, which is one reason family patterns cannot tell us precisely how much of any individual's risk is inherited.

That leaves an uncomfortable gap between knowing that your risk is higher and knowing what will happen to you. Nobody can close that gap with a reliable personal percentage based only on your parent's diagnosis.

It is also worth separating two questions: whether someone might develop fibromyalgia later, and whether symptoms they already have need attention. The second deserves a medical assessment, whatever the family history.

What the “eight times” figure means

Search for hereditary fibromyalgia and you will probably encounter a striking number: eight times more likely.

A frequently cited 2004 family study by Lesley Arnold and colleagues collected information about 533 relatives of 78 people with fibromyalgia and 272 relatives of 40 people with rheumatoid arthritis. The researchers reported an odds ratio of 8.5 for fibromyalgia in the first group compared with the second.

There are two important qualifications. The comparison group consisted of relatives of people with rheumatoid arthritis, rather than a random sample of the general population. And the estimate was imprecise: its 95% confidence interval ranged from 2.8 to 26.

An odds ratio of 8.5 does not mean an 85% chance, eight chances in ten, or a prediction for your child. Odds and probability are different measures. This study also did not follow healthy children throughout their lives to find out how many eventually developed fibromyalgia.

The finding supports a family association. It cannot give a particular family the certainty they may be looking for.

What newer genetic research tells us

A study published in Nature Medicine in July 2026 examined genetic data from more than 2.5 million people, including 54,629 with recorded fibromyalgia diagnoses. It identified 26 associated regions of DNA, with findings pointing toward brain and nerve-cell biology.

This adds to the evidence about fibromyalgia's biological mechanisms. People experiencing its pain did not need to wait for a genetics paper to deserve belief.

The study's genetic risk scores had only modest predictive ability. About 90% of participants with fibromyalgia were of European ancestry, and diagnoses came from health records. Those limits matter when applying the findings to other people.

The paper does not offer a clinically established test that can tell a healthy child whether they will develop fibromyalgia. Nor should percentages describing diagnoses within its study groups be read as a child's lifetime risk.

Should you get a genetic test?

There is currently no established genetic screening test that can reliably answer, “Will I get fibromyalgia?” A consumer DNA score cannot settle that question.

If you are concerned about your family history, you can discuss it at a routine appointment. If you have symptoms, describe those too. According to the US National Institute of Arthritis and Musculoskeletal and Skin Diseases, diagnosis rests on symptoms, medical history and examination; tests may help investigate other possible explanations.

When you or your child has symptoms

Fibromyalgia can affect children as well as adults. The NHS describes widespread pain, fatigue, sleep difficulties and problems with concentration among its symptoms. These symptoms can have other explanations, so recognizing something familiar is a reason to ask questions, rather than assume the diagnosis.

For an adult, it may help to tell a clinician: “My parent has fibromyalgia. I've been having these symptoms, and I'd like to understand what's causing them.”

For a child, start by listening. If pain keeps returning, persists or interferes with sleep, school or ordinary activities, arrange an appointment with their doctor. Explain the family history, but keep the child's own experience at the center of the conversation.

A short note can make the appointment easier:

• Where does it hurt, and when did it start?
• What has changed in their sleep or energy?
• Which activities have become difficult or impossible?
• What else have they noticed?

There is no need to turn home life into constant symptom monitoring. A few concrete observations can be more useful than asking repeatedly whether they feel worse.

A child deserves their own assessment. Their pain should neither be dismissed as copying a parent nor labeled fibromyalgia simply because a parent has it. Fibromyalgia can also coexist with other conditions, so an existing diagnosis does not explain every new symptom. NIAMS describes how clinicians assess these possibilities.

Can you prevent it?

There is no proven routine that guarantees prevention. Fibromyalgia's causes remain incompletely understood, and some people develop it without an identifiable trigger. MedlinePlus describes this uncertainty.

Advice about sleep, activity or managing stress should not become a promise that doing everything “right” will keep a child well. It certainly should not become an accusation if they become ill.

Seek help with health problems that are affecting life now. You do not have to prove that you have prevented every possible future problem.

Talking about risk without passing on guilt

If your child asks whether they will get fibromyalgia too, you can answer honestly without predicting either illness or lifelong good health:

“It can happen in families, but having it doesn't mean you'll have it. If something hurts or you're worried, you can tell me. We'll ask for help when we need it.”

Let their questions set the pace. A younger child may mainly want to know whether you can still spend time together. An adult child may want to talk about their own symptoms, becoming a parent, or the experience of seeing yours dismissed.

Bronwyn C. Minnie's account of growing up with a mother who has fibromyalgia explores the family experience behind this question. It is one person's story, not a forecast for another family.

If you are the parent worrying about what you might have passed on, you don't owe your child an apology for your DNA. You can take their health seriously without making yourself responsible for every uncertainty around it.

If you are the adult child, concern about your own health can sit alongside love for your parent. You are allowed to need reassurance and care yourself.

For the practical side of family life, our guide to helping someone with fibromyalgia offers ways to support someone while respecting their choices. Family support can begin with a simple commitment: when someone says they hurt, listen.
