What primary symptom is associated with fibromyalgia?

Fibromyalgia is primarily characterized by widespread muscle tenderness, which sets it apart from other conditions that may present similar symptoms. This tenderness is often described as a heightened sensitivity to pressure and is a hallmark feature of the disorder. Patients with fibromyalgia commonly report experiencing pain throughout various regions of the body, including muscles, ligaments, and tendons.

While fatigue, stiffness, and swelling can occur in fibromyalgia, they are secondary symptoms. Fatigue is indeed a significant issue for individuals with fibromyalgia, often impacting daily functioning, but the defining feature remains the muscle tenderness. The tenderness is not just localized; it can manifest in multiple areas, indicating a systemic issue rather than an isolated muscle or joint problem. Understanding this primary symptom is crucial for accurate diagnosis and effective management of fibromyalgia.
