Which symptom is commonly associated with fibromyalgia?

Muscle tenderness and pain are indeed the hallmark symptoms of fibromyalgia. This condition is characterized primarily by widespread musculoskeletal pain accompanied by fatigue, sleep, memory, and mood issues. The pain from fibromyalgia is often described as a deep muscle ache or a constant dull ache throughout the body, and pressure points are common sites of discomfort.

This symptom set helps in identifying fibromyalgia, as it distinguishes it from other conditions that may be associated with similar symptoms. While fatigue and dizziness or joint stiffness and swelling can occur in other conditions, they are not as defining of fibromyalgia as muscle tenderness and pain are. Similarly, while headaches and nausea can be related to fibromyalgia, they are not the primary symptoms that define this chronic pain disorder.
