Evidence of the clinical, social, and economic impact of mistaken diagnoses of tendonitis and other chronic painful disorders are analyzed. The objective of this review is to call attention to the possible diagnostic hyper valuation of tendonitis, especially those supposedly multiple or refractory, based on evidence. A review of the literature on chronic painful disorders, such as fibromyalgia, in the context of mistaken diagnosis of tendonitis, as well a review of false positive and ultrasonographic (US) scan diagnostic parameters, is presented. Evidence of therapeutic mistakes were found in 41% and diagnostic mistakes in 70 to 85% of the cases, with proven unpreparedness regarding those disorders in up to 93.7% of the physicians. The diverse repercussions of this epidemic of mistakes are discussed.
