The incidence of the condition rises with age, so that by age 80, 8 percent of people meet the criteria for fibromyalgia, says the NFA.What Causes Fibromyalgia?
According to the Mayo Clinic, repeated stimulation may cause the brains of people with fibromyalgia to change – leading to an increase in chemicals, known as neurotransmitters, that signal pain.
Because the symptoms of fibromyalgia overlap with those of many other conditions, diagnosing fibromyalgia can be difficult.
In many cases, it isn’t clear whether these conditions might trigger the onset of fibromyalgia, or whether they are instead an effect of fibromyalgia – or whether both conditions are due to some other underlying cause.
Among the key differences between RA and fibromyalgia are that RA is an autoimmune disease while fibromyalgia is not, and RA causes inflammation in and around the joints while fibromyalgia does not attack the joints.
Doctors suspect co-occurring fibromyalgia when a person with psoriatic arthritis experiences persistent pain and fatigue, possibly accompanied by other symptoms of fibromyalgia, such as fibro fog, sleep problems, and irritable or overactive bladder.
Getting good information about the disorder is important, too, and a number of organizations, including the National Fibromyalgia Association and the American College of Rheumatology, offer authoritative facts and guidance on managing fibromyalgia.
