The Most Common Associated Disorders of Fibromyalgia

Associated Disorders of FibromyalgiaUnfortunately once you have been diagnosed with fibromyalgia, you may discover you also have one or more other disorders.

If you go on fibromyalgia forums to chat you will often see people with a big list of other issues. It is rare to find someone with ‘just’ fibro!

Don’t panic! It needn’t be a high risk illness, it just seems that fibro sufferers perhaps have an immune system problem that makes them more susceptible to other conditions.

Common Associated Disorders of Fibromyalgia patients include;

  • IBS – Irritable Bowel Syndrome
  • Osteoporosis

  • Psoriatic arthritis
  • Raynaud’s Syndrome

Fibromyalgia is a complicated illness in that it mimics so many other disorders. Therefore it is a difficult condition to diagnose.

There is no blood test that can diagnose fibro, it is merely a diagnosis based on elimination of other illnesses that have similar symptoms to fibro and ones that can be diagnosed through blood or lab testing.

However, there are subtle differences between other illnesses and fibro and by getting as much information as you can about similar disorders, it will help you differentiate fibromyalgia from these disorders.

The most common disorders that people often get confused with fibromyalgia are;

  •    Lyme diseaseAssociated disorders of fibromyalgia
  •    Lupus
  •    Osteoarthritis
  •    Rheumatoid arthritis
  •    Cushing’s syndrome
  •    Hypothyroidism
  •    Polymyalgia Rheumatica
  •    Reflex sympathetic dystrophy syndrome
  •    Cervical spinal stenosis
  •    Multiple Sclerosis


The most important thing is not to panic. Fibromyalgia symptoms change daily and although they may mimic other conditions it doesn’t mean you have other illnesses. It does however make us wonder whether there has been a missed diagnosis.

For example, I have Fibro, Raynaud’s, osteoarthritis and chronic fatigue syndrome. However, I have often thought my symptoms are identical to lupus yet my ANA test always comes back negative, until recently now they believe this positive ANA means I have possible RA or psoriatic arthritis despite not having any history of psoriasis… as you can see it is rather complex to diagnose many of these conditions properly.

So put your trust in your doctor, if you are concerned your symptoms are similar to another condition, ask your doctor to run a few tests. The good thing about most other associated disorders of fibromyalgia is that they can be diagnosed with blood and laboratory tests.
