Polymyalgia rheumatica (PMR) presents uniquely severe clinical symptoms and inflammatory response followed by spectacular improvement in quality of life after glucocorticosteroid (CS) treatment. Severity of symptoms is surprising in older people with an impaired immune response.

In addition, the realities of daily practice dangerously restrict the possibility of accurate differential diagnosis.

Is the diagnosis of PMR possible on the basis of criteria without clinical intuition?
