The diagnosis of fibromyalgia frequently is not well-accepted. The criteria
for classification follow clinical signs and symptoms. They are often foun
d lacking in separating from other pain conditions sufficiently, especially
when clinical features overlap. Subgroups may exist.
Various pathogenetic models resulted in different therapeutic approaches. T
ricyclic antidepressants, serotonin reuptake inhibitors and recently 5-HT3
receptor antagonists are used. So far there is no drug to remove pain subst
antially in ail patients.
