Fibromyalgia vs. Polymyalgia Flashcards
As what type of rheumatic disease is polymyalgia rheumatica (PMR) classified?
- subgroup of vasculitis
As what type of rheumatic disease is fibromyalgia classified?
- non-articular rheumatism (musculoskeletal aches and pains without arthritis).
What types of rheumatic conditions are primary care docs most likely to see?

- hypothyroidism
Should you biopsy a pt with fibromyalgia to diagnose?
- NO. It is a clinical diagnosis.
*** How do we treat fibromyalgia?
- reassurance
- origin of pain
- relief of mechanical stresses (aquatic exercise)
