Polymyalgia rheumatica in a patient presenting with persisting bilateral buttock pain - a case report

Background: Inflammatory conditions often mimic musculoskeletal presentations, causing diagnostic delays in primary and secondary care. Physiotherapists can play a pivotal role in the early recognition, triage, and onward referral for inflammatory conditions such as polymyalgia rheumatica (PMR). While PMR is relatively rare, recognition of its characteristic presentation, alongside elevated serum inflammatory markers, is a much-needed step to initiate appropriate intervention following specialized rheumatological consultation.

Case description: This case details the assessment and diagnosis of a 62-year-old male referred to a secondary care spine center for persisting bilateral buttock pain presumed to be of spinal origin. A thorough initial evaluation by an orthopedic-triage physiotherapist raised the suspicion of PMR upon identification of the following salient inflammatory features: sudden onset of bilateral buttock and shoulder pain and stiffness, morning stiffness lasting one hour, pain aggravated by prolonged inactivity, and a positive response to non-steroidal anti-inflammatory medication.

Outcomes: Further investigations revealed elevated inflammatory markers warranting prompt rheumatology consultation and subsequently confirming the diagnosis of PMR. Early initiation of high dose oral corticosteroid therapy resulted in immediate relief of pain and associated symptoms.

Conclusion: This case highlights the significance of recognizing salient inflammatory features in persistent musculoskeletal complaints, particularly in the context of the evolving scope of physiotherapy roles internationally. While further investigations and rheumatological consultation are required for the definitive diagnosis of many inflammatory conditions, including PMR, greater clinician awareness of salient inflammatory features can aid the earlier identification and subsequent triage of such cases.
