In some studies, nerve growth factor was found to be 4 times higher in the CSF of patients with fibromyalgia than it was in the CSF of individuals without the condition. Nerve growth factor enhances the production of substance P in afferent neurons, increasing an individual's sensitivity to or awareness of pain. Nerve growth factor also may play a role in spreading or redistributing perceived pain signals.
