ESA for Fibromyalgia: WCA Activities and Tips

Fibromyalgia is one of the most common conditions seen in WCA claims, yet it is also one of the most misunderstood. Because there is no definitive diagnostic test and symptoms are invisible, many fibromyalgia claimants are found Fit for Work. This guide shows you how to describe your limitations so the assessor understands the true impact.

Why fibromyalgia scores well - if described properly

Fibromyalgia affects BOTH physical and mental activities. Widespread pain limits mobilising, standing, sitting, reaching, and manual dexterity. Brain fog (fibro fog) limits learning, personal action, and coping with change. Fatigue affects everything. This dual impact means fibromyalgia claimants can potentially score points across 8-10 of the 17 activities.

Physical activities

Mental/cognitive activities

The key argument for fibromyalgia

The WCA asks whether you can do activities reliably - safely, repeatedly, to an acceptable standard, the majority of the time. Fibromyalgia is inherently unreliable. Even if you can sit for an hour today, you might only manage 15 minutes tomorrow. If the bad days are the majority, your form should describe those days, not the good ones.

Scoring example: Standing/sitting (9) + Mobilising (6) + Personal action (6) + Coping with change (6) = 27 points. Nearly double the 15-point threshold.
