Fibromyalgia

Also called Fibromyalgia syndrome or FMS

Fibromyalgia is a long-term condition that causes pain all over the body. People with it may also be more sensitive to pain, feel very tired, sleep poorly and have problems with memory and concentration. The cause is not fully understood but may involve how the brain processes pain signals.

What it is

Symptoms often come and go and can be triggered by stress, poor sleep or changes in the weather.

There is no cure. Regular exercise, talking therapies, good sleep habits and some medicines can help manage it.

Common signs

  • Widespread pain
  • Extreme tiredness
  • Muscle stiffness
  • Difficulty sleeping
  • Problems with memory and concentration (fibro fog)
  • Headaches

How it is usually diagnosed

  • Questions about symptoms
  • Blood tests to rule out other conditions

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood test results
  • Rheumatology letters
  • A symptom diary
  • Treatments tried and their effect

Questions to ask your doctor

  • Could my symptoms be caused by something else?
  • What can I do to manage flare-ups?
  • Which treatments are worth trying?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • New weakness, numbness or loss of bladder or bowel control: get urgent medical help, it is not caused by fibromyalgia
