fibromyalgia pain

What Causes Fibromyalgia?
The causes of fibromyalgia are unknown, but there are
probably a number of factors involved. Many people associate
the development of fibromyalgia with a physically or
emotionally stressful or traumatic event, such as an automobile

accident. Some connect it to repetitive injuries. Others link
it to an illness. People with rheumatoid arthritis and other
autoimmune diseases, such as lupus, are particularly likely
to develop fibromyalgia. For others, fibromyalgia seems to
occur spontaneously.

Many researchers are examining other causes, including
problems with how the central nervous system (the brain
and spinal cord) processes pain.
Some scientists speculate that a person's genes may
regulate the way his or her body processes painful stimuli.

According to this theory, people with fibromyalgia may
have a gene or genes that cause them to react strongly to
stimuli that most people would not perceive as painful.
However, those genes - if they, in fact, exist - have not
been identified.
