What conditions may be related to fibromyalgia?

Some people who have fibromyalgia also report being affected by some of the following problems:

  • chronic tiredness (fatigue)
  • depression and anxiety 
  • headaches
  • joint pain in various parts of their body
  • spasms in either or both legs (restless leg syndrome)
  • dry eyes – sometimes your doctor may recommend tests to check whether this is caused by Sjögren’s syndrome
  • irritable bowel syndrome (IBS)
  • problems with the joint connecting the jawbone to their skull, causing pain in the jaw and areas nearby (temporomandibular joint disorder or TMJD)
  • underactive thyroid (hypothyroidism).

The symptoms of fibromyalgia are often very similar to the symptoms of chronic fatigue syndrome (previously known as myalgic encephalomyelitis or ME). It's not yet clear whether the two conditions are related. People with chronic fatigue syndrome can often recall a viral infection before their fibromyalgia symptoms started. However, they may have less pain than people with fibromyalgia.
