Yes, men get fibromyalgia, but doctors diagnose it in women far more often

Fibromyalgia occurs in men, but the condition is diagnosed in women at a rate of roughly 2 to 7 times higher depending on which study you read. This gap is not because men are biologically protected from fibromyalgia. It exists because doctors are less likely to suspect fibromyalgia in male patients, men are less likely to report widespread pain to a doctor, and the diagnostic criteria themselves were developed and tested mostly on women.

The practical result: men with fibromyalgia often spend years being told their pain is something else—a sports injury, depression, or "just stress"—before reaching a diagnosis. Knowing that men do develop this condition, and understanding why the diagnosis gets missed, matters because fibromyalgia requires specific management approaches that differ from treatment for other chronic pain conditions.

Key Takeaways

  • Men develop fibromyalgia at rates lower than women, but the gap is partly due to underdiagnosis rather than biological protection.
  • Doctors often attribute fibromyalgia symptoms in men to other causes—injury, aging, depression, or overwork—and may not consider fibromyalgia as a diagnosis.
  • Men are less likely than women to report widespread pain to a doctor or to seek care for pain that does not follow an obvious injury pattern.
  • Fibromyalgia in men presents with the same core symptoms as in women: widespread pain, sleep disruption, fatigue, and cognitive difficulties.
  • Getting a diagnosis in men may take longer, but the same diagnostic criteria and treatment approaches apply regardless of sex.

Why the diagnosis rate differs between men and women

The gap between diagnosis rates in men and women reflects three overlapping problems. First, fibromyalgia was historically studied and described in female populations, so the clinical picture that doctors learn is often anchored to how it presents in women. Second, doctors carry assumptions about pain in men—that it should have a clear mechanical cause, that men tolerate pain differently, or that widespread pain in a man points toward depression or malingering rather than a medical condition. Third, men themselves report pain differently: they are more likely to minimize symptoms, less likely to seek care for pain without an obvious injury, and more likely to frame pain as a performance problem ("I can't lift like I used to") rather than a symptom requiring medical attention.

Research on diagnostic delay shows that men with fibromyalgia often receive other diagnoses first—chronic fatigue syndrome, depression, arthritis, or repetitive strain injury—before fibromyalgia is considered. Some men never receive a fibromyalgia diagnosis at all and instead manage their condition under a different label or without a clear diagnosis.

How fibromyalgia presents differently in men

The core symptoms of fibromyalgia are the same in men and women: widespread musculoskeletal pain, non-restorative sleep, fatigue, and cognitive symptoms sometimes called "fibro fog." However, men more often describe their pain in terms of performance loss or functional limitation rather than pain itself. A man might say "I can't do the work I used to" or "My strength is gone" rather than "I have widespread pain." This difference in how men frame symptoms can lead doctors to miss fibromyalgia and instead investigate thyroid function, testosterone levels, or depression.

Men with fibromyalgia also report higher rates of comorbid conditions like sleep apnea and mood disorders, though it remains unclear whether these occur more frequently in men with fibromyalgia or whether men are simply more likely to be diagnosed with these conditions when they seek care. The fatigue component of fibromyalgia in men is sometimes attributed to age, overwork, or low testosterone rather than recognized as part of a fibromyalgia syndrome.

What happens when fibromyalgia goes undiagnosed in men

Delayed or missed diagnosis creates real consequences. Without a fibromyalgia diagnosis, men may pursue treatments that do not address the underlying condition—such as repeated imaging, injections, or surgery for pain that is actually neuropathic and widespread. They may be prescribed opioids for pain management when evidence-based fibromyalgia treatment emphasizes exercise, sleep hygiene, and sometimes specific medications like pregabalin or duloxetine. They may also face workplace or social skepticism about their symptoms if no diagnosis exists to validate their experience.

Men may also delay seeking treatment altogether, interpreting fibromyalgia symptoms as a sign of aging, deconditioning, or personal weakness rather than a medical condition. This can lead to progressive deconditioning, worsening sleep, and increased pain—a cycle that fibromyalgia-specific treatment can interrupt.

Getting a fibromyalgia diagnosis as a man

The diagnostic criteria for fibromyalgia are the same regardless of sex. A doctor will assess widespread pain using the Widespread Pain Index (WPI), which maps pain across the body, and evaluate symptom severity using the Symptom Severity Scale (SSS), which measures fatigue, sleep problems, and cognitive symptoms. There is no blood test or imaging study that confirms fibromyalgia; diagnosis is clinical, based on symptom pattern and duration.

If you are a man seeking a fibromyalgia diagnosis, be specific about your symptoms: describe pain location and pattern, how long you have had it, what makes it better or worse, how it affects your sleep and daily function, and any other symptoms like fatigue or memory problems. If your primary care doctor does not seem to consider fibromyalgia, ask directly whether it fits your symptom pattern, or ask for a referral to a rheumatologist, who specializes in fibromyalgia diagnosis and treatment.

Treatment approaches are the same regardless of sex

Once diagnosed, fibromyalgia treatment does not differ by sex. The foundation is aerobic exercise and strength training, adjusted to your current fitness level and pain tolerance. Sleep improvement—through sleep hygiene, treatment of sleep disorders, or sometimes medication—is equally important. Cognitive behavioral therapy or other psychological approaches help manage the emotional impact of chronic pain and can reduce symptom severity.

Medications used for fibromyalgia include pregabalin (Lyrica), duloxetine (Cymbalta), and milnacipran (Savella), all approved by the FDA for fibromyalgia. Some doctors also prescribe low-dose naltrexone or other medications off-label. The choice depends on your other health conditions, other medications you take, and how your body responds. A rheumatologist or pain specialist can help determine which approach makes sense for your situation.

Why men may hesitate to seek or accept a fibromyalgia diagnosis

Some men resist a fibromyalgia diagnosis because it conflicts with how they understand themselves or their bodies. Fibromyalgia is sometimes perceived as a "women's condition" or as psychosomatic, and men may worry that accepting the diagnosis means accepting weakness or admitting to a mental health problem. Others fear that a fibromyalgia diagnosis will limit their work or social identity, or that it will not be taken seriously by employers or healthcare providers.

These concerns are understandable but worth examining. Fibromyalgia is a real neurobiological condition, not a psychological weakness. Accepting a diagnosis does not change your capabilities; it changes your understanding of what is happening in your body and opens access to treatments that work. Many men find that a fibromyalgia diagnosis, while initially unwelcome, actually improves their quality of life by validating their experience and pointing toward effective management strategies.

Frequently Asked Questions

Can fibromyalgia develop after an injury or trauma in men?

Fibromyalgia can emerge or worsen after physical or emotional trauma, though the relationship is not fully understood. Some men develop widespread pain months or years after an injury that seemed to heal. This pattern can make fibromyalgia harder to recognize because the pain appears to be injury-related rather than a separate condition. If pain spreads beyond the original injury site or persists long after healing should be complete, fibromyalgia may be worth investigating.

Is fibromyalgia in men related to low testosterone?

Fibromyalgia and low testosterone are separate conditions, though they can occur together. Some men with fibromyalgia have low testosterone, and testosterone replacement may improve some symptoms like fatigue or mood. However, testosterone replacement alone does not treat fibromyalgia. If you have fibromyalgia symptoms and low testosterone, both conditions should be addressed—testosterone levels checked and adjusted if needed, and fibromyalgia managed with exercise, sleep support, and appropriate medication.

Will a fibromyalgia diagnosis affect my work or disability status?

A fibromyalgia diagnosis itself does not automatically may have access to you for disability or workplace accommodations. However, if fibromyalgia significantly limits your ability to work, you may be able to request accommodations under the Americans with Disabilities Act (ADA) or pursue disability benefits. The strength of your case depends on how fibromyalgia affects your specific job and your medical documentation. A rheumatologist or occupational medicine doctor can help document functional limitations.

How long does it typically take to get a fibromyalgia diagnosis in men?

There is no standard timeline, but men often experience longer diagnostic delays than women—sometimes years. The delay occurs because fibromyalgia may not be considered early, or because other conditions are investigated first. Seeking care from a rheumatologist rather than a primary care doctor can shorten the diagnostic process, since rheumatologists are trained to recognize fibromyalgia patterns and have the diagnostic criteria at hand.

Can fibromyalgia get worse over time in men?

Fibromyalgia is not progressive and does not cause permanent damage to joints, muscles, or organs. However, symptoms can fluctuate or worsen if the condition is not managed—particularly if pain leads to inactivity, which worsens deconditioning and sleep problems. With appropriate treatment, including exercise and sleep management, many men see symptom improvement or stabilization over time.
