Fibromyalgia Self-Assessment & Symptom Check
1
What this questionnaire measures
The check structures pain distribution, fatigue, sleep, and cognitive symptoms with an ACR-oriented WPI and symptom-severity logic.
2
When this questionnaire is useful
It helps when pain affects multiple body regions and the overall symptom pattern needs clearer structure before a clinician conversation.
3
What the result does not do
The self-assessment does not diagnose fibromyalgia or exclude other causes of pain, fatigue, sleep disturbance, or cognitive symptoms.
What does it check?
ACR main criterion
Widespread Pain Index (WPI)
Counts painful body regions across 19 defined areas. A WPI ≥ 7 is one of the main ACR 2010 criteria.
ACR main criterion
Symptom Severity Scale (SS)
Rates severity of fatigue, sleep, and cognitive symptoms. An SS ≥ 5 combined with WPI ≥ 7 meets the ACR criterion.
Assessed domain
Fatigue
Persistent physical and mental exhaustion that is not relieved by sleep or rest.
Assessed domain
Sleep quality
Unrefreshing sleep, difficulty falling or staying asleep, as part of the symptom severity scale.
Assessed domain
Cognitive symptoms
Concentration and memory difficulties (fibro-fog) as part of the ACR symptom severity scale.
Supplementary criterion
Somatic symptoms
Additional symptoms describing overall symptom burden.
- Headaches (≥ 3 months)
- Abdominal pain / irritable bowel
- Depressive mood
When it helps, its limits & next steps
Important limits
not a confirmed diagnosis and not a replacement for medical evaluation
not for acute, suddenly severe, or neurological red flag symptoms
not an exclusion of other pain causes
After the result
interpret WPI and symptom severity together
discuss persistent or limiting symptoms with a clinician
if exertion worsens symptoms, also review PEM and ME/CFS context
Common questions
Everything about the check
Before you start – the most important answers at a glance.
Can a fibromyalgia self-test diagnose fibromyalgia?
No. The check can show a fibromyalgia-oriented pattern. Diagnosis requires medical assessment and exclusion of other causes.
What do WPI and symptom severity mean?
The WPI counts painful body regions. The symptom severity score considers symptoms such as fatigue, sleep, and cognitive difficulties.
When should I discuss the result?
If pain, exhaustion, or sleep problems persist, worsen, or limit daily life, the result should be interpreted medically.
What do WPI and Symptom Severity Score mean?
The WPI counts painful body regions. The Symptom Severity Score covers symptoms such as fatigue, unrefreshing sleep, and cognitive difficulties.
Can an online fibromyalgia test replace diagnosis?
No. An online check can structure pain distribution and symptom severity, but it cannot replace medical diagnosis or exclusion of other causes.
When should I also consider ME/CFS or PEM context?
If symptoms worsen disproportionately and often with delay after physical, cognitive, or emotional exertion, PEM and ME/CFS context should also be reviewed.
