Joint Muscle Pain

• Gout & Pseudogout (Crystal Arthropathies) - Acute Attack Management & Chronic Prevention Strategies: Diagnosing (often clinical, supported by serum uric acid levels; joint aspiration for crystal analysis if diagnostically uncertain or to rule out septic arthritis) and managing acute gout or pseudogout attacks with appropriate anti-inflammatory medications (NSAIDs like naproxen/indomethacin, colchicine, oral or intra-articular corticosteroids).

Initiating treatment with low-dose corticosteroids (e.g., prednisone 12.5-25 mg daily) which usually results in a rapid and dramatic improvement in symptoms, thus supporting the diagnosis. Vigilantly screening for and differentiating from Giant Cell Arteritis (GCA/Temporal Arteritis), which can co-exist with PMR (or occur independently) and requires urgent higher-dose steroid therapy and specialist (rheumatology/ophthalmology) referral to prevent irreversible vision loss.
