Here are THE symptoms of Fibromyalgia: Neurological manifestations: Neurological difficulties are often present such as hypertonic and hypotonic muscles; musculoskeletal asymmetry and dysfunction involving muscles, ligaments and joints; atypical patterns of numbness and tingling; abnormal muscle twitch response, muscle cramps, muscle weakness, and fasciculations. Headaches, temporomandibular joint disorder, generalized weakness, perceptual disturbances, spatial instability, and sensory overload phenomena often occur. • Neurocognitive manifestations: Neurocognitive difficulties usually are present. These include impaired concentration and short-term memory consolidation, impaired speed of performance, inability to multi-task, easy distractibility, and/or cognitive overload. • Fatigue: There is persistent and reactive fatigue accompanied by reduced physical and mental stamina, which often interferes with the patient’s ability to exercise. • Sleep dysfunction: Most FMS patients experience unrefreshing sleep. This is usually accompanied by sleep disturbances including insomnia, frequent nocturnal awakening, nocturnal myoclonus, and/ or restless leg syndrome. • Autonomic and/or neuroendocrine manifestations: These manifestations include cardiac arrhythmias, neurally mediated hypotension, vertigo, vasomotor instability, sicca syndrome, temperature instability, heat/cold intolerance, respiratory disturbances, intestinal and bladder motility disturbances with or without irritable bowel or bladder dysfunction, dysmenorrhea, loss of adaptability and tolerance for stress, emotional flattening, lability, and/or reactive depression. • Stiffness: Generalized or even regional stiffness that is most severe upon awakening and typically lasts for hours as occurs with active rheumatoid arthritis. It can return during periods of inactivity during the day.
