Because
fibromyalgia is difficult to diagnose and sometimes
occurs with other muscle or joint diseases or chronic pain conditions,
determining just how many people have this condition is difficult. However, it
is estimated that 3 to 6 million people in the United States have
fibromyalgia.1
Women are affected far more often than men, although men and children
also get fibromyalgia. While fibromyalgia can occur at any age, the chance of
getting this condition increases as you age and seems to be greatest after age
60.2 Those who are most likely to be diagnosed
include:1
- People who also have a rheumatic condition, such
as
lupus or
rheumatoid arthritis.
- Women who have
another family member with fibromyalgia, although the reasons for this are not
clear.
About half of people with fibromyalgia say their symptoms started
after they had been ill from an infectious disease such as Lyme disease.
Although research is still being done, no connection between infectious disease
and fibromyalgia has been firmly established.3
