Fibromyalgia: the clinical syndrome

Area of Science:

• Rheumatology
• Pain Medicine
• Musculoskeletal Disorders

Background:

• Fibromyalgia is a complex condition with core features like widespread pain and tenderness.
• Characteristic symptoms include fatigue, non-refreshed sleep, and morning stiffness.
• Commonly associated symptoms include paresthesia, irritable bowel syndrome, and functional disability.

Purpose of the Study:

• To describe the core, characteristic, and common features of fibromyalgia.
• To report the prevalence of fibromyalgia in various patient populations.
• To highlight the role of evolving diagnostic criteria in patient identification.

Main Methods:

• Literature review and synthesis of existing data on fibromyalgia.
• Analysis of patient data to determine symptom frequency.
• Examination of diagnostic criteria evolution.

Main Results:

• Fibromyalgia presents with consistent widespread pain and tenderness.
• Fatigue, poor sleep, and morning stiffness are highly prevalent symptoms.
• The syndrome affects 2.1% of family practice patients and up to 20% of rheumatology patients.

Conclusions:

• Fibromyalgia is a prevalent musculoskeletal disorder with distinct symptom clusters.
• Accurate diagnosis is crucial for effective patient management and research.
• Ongoing refinement of diagnostic criteria improves patient identification and study validity.
