Question

Vicki, age 36, presents with symptoms resembling both fibromyalgia and chronic fatigue syndrome. Which of the following is more characteristic of fibromyalgia than of chronic fatigue syndrome?

1) Muscle pain and tenderness
2) Extreme fatigue
3) Difficulty concentrating
4) Headaches

Answer 1

Muscle pain and tenderness are more characteristic of fibromyalgia than chronic fatigue syndrome, which is primarily defined by extreme fatigue.

Step-by-step explanation:

The question asks which symptom is more characteristic of fibromyalgia compared to chronic fatigue syndrome (CFS). The most distinguishing feature muscle pain and tenderness, which strongly points to fibromyalgia. While both conditions can involve some degree of muscle pain, the degree of tenderness and the specific locations of tenderness, known as tender points, are more defining characteristics of fibromyalgia. Chronic fatigue syndrome, on the other hand, is primarily characterized by extreme fatigue that is not significantly relieved by rest.

Difficulty concentrating, known as 'fibro fog,' and headaches are also common in fibromyalgia but these symptoms can also be present in chronic fatigue syndrome, making them less distinctive. Therefore, the most characteristic symptom of fibromyalgia in contrast to chronic fatigue syndrome is muscle pain and tenderness, which answers the student's question.
