Patients eventually diagnosed as having the fibromyalgia syndrome often have symptoms which suggest alternate diagnoses such as peripheral neuropathy, spondylitis, metabolic myopathy, polymyalgia, early rheumatoid arthritis, early systemic lupus erythematosus or a chronic fatigue syndrome. Delay in diagnosis of fibromyalgia often proves costly and frustrating to the patient and may lead to inappropriate therapy.
