As usual, a few number of the persons claiming they have these symptoms, are drug seekers and since the symptoms are largely subjective, there is no way to discount these symptoms as malingering.
Those with real symptoms should first have their physician rule out any type of autoimmune disease like Lupus or Rheumatoid arthritis. More recent studies have shown that Fibromyalgia patients suffer from a certain sleep disorder called alpha-delta anomaly. Normal sleep patterns include five stages of sleep, ending with stage 5, when we commonly dream. Alpha-Delta disorder occurs when people rarely reach stage 5, spending a large percentage of time in stage 2. This stage is when people commonly say when interrupted, I wasn't asleep yet. Stage three is the beginning of REM sleep. The anomaly causes intrusion of alpha sleep into delta sleep, never allowing the person to get restorative sleep.
Also, many Fibromyalgia patients are found to have mild to moderate sleep apnea, in combination with the sleep disorder. Some Neurologists now seem to feel that the lack of restorative sleep is the cause of the hyperactivity in the nerve endings, resulting in increased pain. Many have started their patients on C-PAP machines with patients eventually getting more restorative sleep and disappearance of the symptoms, altogether within a six month period.
Since, most patients with Fibromyalgia suffer from one or both of the sleep disorders, it is becoming easier to determine who actually needs treatment and what kind.
