What is the main symptom of polymyalgia rheumatica that lasts over 45 minutes?

✓ Accepted answer

The main symptom of polymyalgia rheumatica (PMR) that lasts over 45 minutes is significant morning stiffness in the muscles around the shoulders, neck, and hips.

• Clinical Marker: According to the UK’s National Health Service (NHS), this prolonged morning stiffness is the hallmark feature clinicians look for to distinguish PMR from other conditions. Unlike osteoarthritis, where stiffness typically resolves within 30 minutes, PMR stiffness persists for at least 45 minutes.
• Diagnostic Threshold: Healthcare providers in both the US and UK generally require this symptom to be present for at least two weeks to consider a formal diagnosis. It usually affects both sides of the body symmetrically.
• Associated Symptoms: In addition to stiffness, patients often report extreme fatigue, loss of appetite, and unexplained weight loss. The pain is typically described as a deep aching rather than sharp joint pain.
• Medical Evaluation: In the US, rheumatologists often order a blood test to measure the C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), which are usually elevated in PMR. In the UK, GPs refer patients for these blood tests to rule out other causes like rheumatoid arthritis.
• Response to Treatment: A key diagnostic clue is the rapid and dramatic improvement in symptoms within 24 to 72 hours after starting low-dose corticosteroids, a response consistent with findings from the American College of Rheumatology.
