At least one in 10 of us suffer some sort of troublesome, long-term (chronic) pain. But not all have fibromyalgia.
People with fibromyalgia have chronic widespread pain - including musculoskeletal aches, pain and stiffness, and soft tissue tenderness - in many areas across the body.
This affects other systems like the brain, impacting a person's ability to concentrate and remember things. People who have fibromyalgia often refer to this as the "fibro fog". It can affect sleep patterns, emotions, and many other aspects of everyday living.

So what causes fibromyalgia?
When investigations can find no other cause for widespread chronic pain, it's generally diagnosed as fibromyalgia.
We don't know exactly what causes fibromyalgia, but genetics, environment, hormonal and neural (brain and central nervous system) factors are all believed to play a role.
Research indicates genes may be responsible for up to 50 percent of susceptibility to the condition. The latest research indicates the body's immune system is involved, too.
An online survey of 596 people with fibromyalgia found a few common causes reported by participants.
Around two thirds of people could relate the start of their symptoms to a specific incident or event, such as a physical injury, a period of sickness that might have involved surgery, or a stressful life event.
Notably, many of those surveyed said they experienced negativity and stigma when trying to explain and authenticate their symptoms to professionals, their families, and their communities.
How is it treated?
Everyone experiences treatments differently, and what works for one person may not work for another. But the main treatments focus on pain relief.
The drugs pregabalin and duloxetine work by altering the neurotransmitters in the brain (gamma amino butyric acid and serotonin), and are effective for many people.
