Fibromyalgia (FM) syndrome is predominantly related to generation and persistence of central sensitization, which is an aggravating factor for chronic headaches. This review aims to examine the last 11 years of studies on FM and primary headache comorbidity, focusing on prevalence, clinical features and treatments. Chronic forms of migraine and tension-type headache show a high frequency of FM comorbidity. The symptoms characterizing headache patients presenting with FM comorbidity are high headache frequency, poor sleep quality, pericranial tenderness, anxiety and reduction of physical performances. The effects of headache-preventive drugs on factors favoring FM comorbidity were poorly evaluated. Nonpharmacological approaches such as transcranial magnetic stimulation may be an option for treatment of chronic migraine associated with FM.

Review
Possible causes of comorbidity between fibromyalgia & primary headachesFibromyalgia (FM) is a chronic pain syndrome of unknown etiology characterized by diffuse pain over more than 3 months and tenderness in at least 11 tender point sites out of 18 [1]. The diagnostic criteria have recently been revised in view of the full consideration of the complexity of symptoms associated with generalized pain, including nonrestorative sleep, fatigue and cognitive dysfunction, with less importance attributed to the number of painful tender points [2].The causes of F...
