Polymyalgia rheumatica is a clinical syndrome in which there is persistent muscle ache /stiffness at multiple sites. The neck, shoulder and hip regions are most commonly affected.
Confirming the diagnosis
There is no definitive test for this condition. Diagnosis is based on the characteristic history. Other possible causes for the symptoms need to be ruled out. An elevated erythrocyte sedimentation rate or C-reactive protein level and a rapid response to oral corticosteroids (predinisone) help to confirm the diagnosis.
The relevant medical specialist is a rheumatologist.

Onset may be sudden or gradual. Once the diagnosis has been confirmed, clinical onset can be backdated to when relevant, continuing sysmptoms first developed.
The only worsening factor is for inability to obtain appropriate clinical management. The normal course of isolated, treated polymyalgia rheumatica is for the condition to gradually resolve over 1 to 2 years. Complications from steroid treatment can arise but these are separate conditions and not worsening of the polymyalgia rheumatica.
