Fibromyalgia - Causes


Causes of Secondary Fibromyalgia

Secondary fibromyalgia has the characteristic symptoms of fibromyalgia but, unlike primary fibromyalgia, a specific cause can be identified. Possible causes include:

  • Physical injury -- In one study, for example, secondary fibromyalgia developed in over 20% of patients who had neck injuries. The symptoms are identical to those of primary fibromyalgia but are harder to treat. Another study reported a high rate of fibromyalgia in workers who had repetitive stress injuries, although it is not clear which condition came first.
  • Ankylosing spondylitis
  • Surgery
  • Lyme disease
