Select the disease that is associated (and exacerbated) by chronic stress and anxiety.

Fibromyalgia is a syndrome characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas. It is known that chronic stress and anxiety can exacerbate the symptoms of fibromyalgia. These emotional states may impact the body's pain response and lead to heightened sensitivity to pain, which is a hallmark of fibromyalgia.

Stress and anxiety can influence various physiological systems, including hormonal and immune responses, potentially leading to increased inflammation and pain. Many individuals with fibromyalgia report that stress triggers or worsens their symptoms. Thus, recognizing the role of chronic stress and anxiety in this condition is crucial for effective management and treatment strategies.

In contrast, conditions like Parkinson's Disease, Multiple Sclerosis, and Muscular Dystrophy are primarily neurological or genetic disorders, with their symptomatology and progression not directly tied to stress and anxiety in the same way fibromyalgia's symptoms are. Hence, while stress may play roles in different health conditions, the link between chronic stress, anxiety, and fibromyalgia is particularly well established.
