Fibromyalgia after trauma is medicine’s contested territory — and insurers exploit the controversy. The honest position: post-traumatic onset is recognized in clinical literature, diagnosis follows established criteria, and contested does not mean compensable-never. These claims are harder; they are not hopeless.
The Medical Picture
- What it is: a chronic widespread-pain condition with fatigue and cognitive symptoms, diagnosed clinically — MedlinePlus outlines the criteria.
- The trauma link: onset following physical trauma is reported in a meaningful share of cases; causation opinions come from treating physicians applying the literature, not from webpages.
- The proof burden: credible diagnosis, rule-outs done properly, and consistent longitudinal records matter more here than in any other crash claim.
What It Means for Your Claim
Expect a causation fight and build for it: rheumatology-level diagnosis, a clean pre-crash record, and day-to-day impact documentation. These cases reward early legal involvement precisely because the record has to be built deliberately rather than assembled later.
Frequently Asked Questions
The insurer says fibromyalgia can’t be proven objectively. Do I lose?
No — clinical diagnoses without lab markers are still diagnoses, and courts hear them regularly. Credibility and consistency substitute for imaging; that’s a documentation strategy, not a dead end.
My symptoms appeared days after the crash. Does that hurt my claim?
It’s medically common and legally manageable — document promptly once symptoms appear and treat consistently. The mistake is toughing it out; treatment gaps become the defense’s favorite exhibit.
Does this injury count as ‘serious’ under my limited tort policy?
It depends on impairment of function, not the diagnosis label — a fought-over standard worth professional analysis, never an adjuster’s checkbox. Our limited tort explainer covers the stakes.
