Question explored with the scientific record
is fibromyalgia commonly diagnosed for MS?
The short version: the evidence you retrieved does not answer whether fibromyalgia is commonly diagnosed for MS.
The question asks about a diagnostic substitution or misdiagnosis rate—how often fibromyalgia is given to people who actually have multiple sclerosis. None of the studies you provided test that. One cross-sectional study of 181 MS patients found that 66% reported pain [5], but it did not report how many of them carried a fibromyalgia diagnosis, let alone whether that diagnosis was correct or masking MS. The 2025 HERV study [4] distinguished ME/CFS from fibromyalgia at the molecular level, but it did not examine MS at all. The Lyme disease review [2] mentions that fibromyalgia overlaps with Lyme symptoms and can be a misdiagnosis, but that is a different disease entirely.
The evidence here is off-scope. It describes fibromyalgia’s diagnostic criteria [1], its central sensitization mechanisms [9], and its molecular fingerprint [4], but it never compares fibromyalgia diagnosis rates in MS patients versus controls, nor does it track how often MS is initially labeled as fibromyalgia. Without that comparison, the question cannot be answered from this evidence.
My call: the retrieved evidence does not address the question. Confidence: not clear—the gap itself is the finding.
