Which term best describes muscle pain?

• A. Myopathy
• B. Fibromyalgia
• C. Tendinopathy
• D. Myalgia

Answer: (D)

Muscle pain is described by the term myalgia. This label is used when a person reports discomfort in the muscles themselves, without implying a primary muscle disease. It helps distinguish muscle-origin pain from other related problems: myopathy refers to a primary muscle disease that often involves weakness and more systemic signs; tendinopathy describes pain originating from a tendon near a joint; and fibromyalgia is a broader chronic pain condition with widespread musculoskeletal pain plus fatigue and other symptoms. So, when the symptom is simply muscle pain, the correct term is myalgia.
