Contributing factors may include:
• Central nervous systems issues
• Repetitive injuries
• Rheumatoid arthritis and/or Lupus
• Traumatic physical or psychological episode (Post-traumatic stress disorder)
• Family history can make one more vulnerable to developing the syndrome.
Besides the above causes, other risk factors include gender—women are ten times more likely to develop the syndrome—and age—Fibromyalgia is more commonly diagnosed between 20 and 50 years old. Furthermore, sleep disorders have been seen as both a symptom and a possible cause of Fibromyalgia. Patients who suffer from sleep disorders as restless leg syndrome or sleep apnea have increased risk of having Fibromyalgia.
