Frequently asked questions
Is fibromyalgia a form of arthritis?
No. Fibromyalgia doesn't damage joints or cause inflammation. However, it commonly occurs alongside arthritis and is treated by similar rheumatology teams.
How is fibromyalgia diagnosed in the UK?
Diagnosis is clinical — based on widespread pain lasting over 3 months, plus fatigue, sleep and cognitive symptoms. Blood tests are used to rule out other conditions.
What is fibro fog?
Fibro fog is the cognitive symptom of fibromyalgia — short-term memory lapses, word-finding difficulties and trouble concentrating. It improves with better sleep, pacing and exercise.
Can fibromyalgia be cured?
There is no cure, but with self-management, exercise, medication and CBT, many people significantly reduce symptoms and stay in work and family life.
Does fibromyalgia get worse over time?
Fibromyalgia is not progressive — it doesn't damage tissue. Symptoms fluctuate, often worsening with stress, poor sleep or overdoing activity, and easing with steady self-management.
