Symptoms of fibromyalgia

As well as widespread pain, other symptoms of fibromyalgia include:

  • increased sensitivity to pain
  • muscle stiffness
  • difficulty getting to sleep or staying asleep, which can make you feel very tired (fatigue)
  • problems with mental processes (known as "fibro-fog"), such as difficulty concentrating or remembering things
  • headaches
  • irritable bowel syndrome (IBS), a digestive condition that causes stomach pain and bloating
  • feelings of frustration, worry or low mood

It's also suggested that some people are more likely to develop fibromyalgia because of genes inherited from their parents.

In many cases, the condition appears to be triggered by things that are physical or emotional like an injury, an infection or stress.
