Fibromyalgia and Disability Insurance: Fighting an Invisible Condition

There's no blood test for fibromyalgia — and insurers use that against you
Fibromyalgia is a chronic pain condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive difficulties. It affects an estimated 2-4% of Canadians. Despite being recognized by the medical community as legitimate and disabling, insurance companies routinely deny fibromyalgia claims.
How insurers deny fibromyalgia claims
The most common tactics: "No objective findings" — fibromyalgia doesn't show up on blood tests or imaging. "Self-reported symptoms" — they dismiss your pain as subjective. Surveillance — they film you on a good day. Biased IMEs — their hired doctor minimizes your symptoms after a brief exam.
What the law actually says
Ontario courts have consistently recognized fibromyalgia as a legitimate, disabling condition — even without objective diagnostic testing. The legal standard is not whether your condition can be proven by a blood test. It's whether your symptoms prevent you from reliably performing the duties of your job.
How we build fibromyalgia cases
We prove fibromyalgia disability using: pain specialist and rheumatologist reports, functional capacity evaluations, detailed pain diaries, evidence of failed treatment attempts, psychological assessments showing pain's impact on cognition and mood, and independent medical reviews.
