Living with fibromyalgia exhausts you physically, emotionally, and financially. You likely manage chronic pain, deep fatigue, sleep disruption, and cognitive challenges that make full-time work impossible.
Despite the severe impact of this condition, insurance companies frequently deny short-term and long-term disability claims for fibromyalgia. Many people feel shocked when insurers refuse benefits, even with strong support from their doctors.
At Kotak Law, we regularly help Canadians fight back against unfair disability claim denials. This guide breaks down why insurers often reject fibromyalgia claims, the hurdles you face, and the steps you can take to protect your livelihood.
The Reality of Fibromyalgia in the Workplace
Fibromyalgia is a severe chronic condition. Symptoms change from day to day and often include:
- Widespread muscle and joint pain
- Profound fatigue and sleep disturbances
- Cognitive dysfunction or “fibro fog”
- Headaches and migraines
- Stiffness and sensitivity to touch
- Overlapping anxiety and depression
You might experience periods where symptoms temporarily ease, only to face a debilitating flare-up that stops you from performing basic daily tasks. For many, this unpredictability makes holding down a job impossible. Even sedentary office work becomes unmanageable when pain, fatigue, and memory issues take over.
Why Do Insurers Deny Fibromyalgia Claims?
Insurance companies use several common arguments to deny or terminate disability benefits for people living with fibromyalgia.
The “Lack of Objective Evidence” Excuse
Insurers prefer concrete, measurable proof of disability, such as MRI findings, abnormal X-rays, or clear bloodwork. Because doctors diagnose fibromyalgia based on clinical evaluation, reported symptoms, and medical history, insurers often argue there is a lack of “objective medical findings.”
Canadian courts repeatedly recognize that fibromyalgia can cause total disability despite a lack of abnormal imaging. The absence of an abnormal test result does not mean you can work full time.
Symptom Fluctuation and Surveillance
People with fibromyalgia have good days and bad days. You might push through the pain to attend a brief family event or buy groceries, only to spend the next three days recovering in bed.
Insurers often conduct video surveillance or monitor your social media accounts. They look for isolated moments where you appear functional and use those snapshots to argue that you can return to work. They ignore the broader reality of your condition and the exhaustion that follows physical exertion.
Minimizing “Invisible Illnesses”
Fibromyalgia is an invisible illness. You might look healthy on the outside while fighting severe pain on the inside. Insurance companies sometimes use this against you, claiming you “look fine” or that you exaggerate your symptoms. They often overlook how extreme fatigue and cognitive impairments ruin your ability to concentrate, meet deadlines, or interact with clients.
Overlapping Mental Health Conditions
Chronic pain rarely exists in isolation. Many people with fibromyalgia also experience depression, anxiety, or chronic stress. Insurers often try to separate these conditions to downplay how they interact. In reality, pain and mental health symptoms worsen each other, creating a combined effect that severely limits your ability to work.
The Two-Year “Any Occupation” Hurdle
Many long-term disability policies change their definition of disability after 24 months. Initially, you receive benefits if your condition prevents you from doing your own specific job.
After two years, the test changes. The insurer will only continue paying benefits if you cannot perform any occupation suited to your education, training, or experience. Insurers frequently use this shift to cut off benefits. They argue that even if you cannot handle physical tasks, you can still perform sedentary or part-time work.
Independent Medical Examinations (IMEs)
During your claim, the insurance company will likely send you to an Independent Medical Examination (IME). The insurer pays the doctor conducting this functional assessment. These doctors often write reports that favour the insurance company, failing to capture the fluctuating, severe nature of your daily symptoms. Insurers rely heavily on these reports to justify terminating your benefits.
Should You Appeal a Denial?
When insurers deny a claim, they usually invite you to submit an internal appeal. Proceed with caution. Internal appeals stay within the insurance company, meaning the same organization reviews its own decision. This process often wastes valuable time while legal limitation periods tick away.
Before you file an appeal, seek independent legal advice. You have the right to bypass the internal appeal process and file a lawsuit against the insurance company. Legal action allows you to seek compensation for unpaid benefits, future benefits, legal costs, and sometimes aggravated damages.
Building a Winning Case
A successful fibromyalgia disability claim requires detailed evidence. To strengthen your case, you need thorough medical records that document:
- The severity of your pain and fatigue
- Specific functional limitations and work restrictions
- Cognitive impairments
- Failed treatment attempts and medication side effects
- A consistent history of your symptoms over time
Reports from specialists, occupational therapists, psychologists, and vocational experts will heavily support your case.

Frequently Asked Questions
Can I get long-term disability benefits for fibromyalgia?
Yes. You can qualify for disability benefits if your fibromyalgia symptoms prevent you from performing the duties of your occupation (or any occupation, depending on your policy).
Why do insurers deny fibromyalgia claims so often?
Insurers frequently deny these claims because fibromyalgia lacks objective diagnostic findings, like abnormal X-rays or blood tests, making it easier for them to dispute the severity of your pain.
Can insurance companies watch me or check my social media?
Yes. Insurers often use video surveillance and review public social media posts to find footage of you performing tasks they believe prove you can work.
What happens after I receive long-term disability benefits for two years?
After roughly 24 months, most policies shift from an “own occupation” definition to an “any occupation” definition. Insurers often use this transition to terminate benefits, arguing you can do lighter or different work.
