What condition is characterized by pain and tenderness without joint involvement?

Fibromyalgia is recognized as a condition that is characterized by widespread pain and tenderness throughout the body, but it does not specifically involve the joints in the same way that conditions like arthritis do. Individuals with fibromyalgia often experience symptoms such as fatigue, sleep disturbances, and cognitive issues, commonly referred to as "fibro fog," in addition to the widespread pain.

The absence of joint involvement is a crucial distinguishing factor for fibromyalgia compared to other options; conditions like osteoarthritis and gout primarily affect the joints and lead to more localized pain and swelling. Bursitis, while involving inflammation, also affects the cushioning sacs near joints, leading to pain in those specific areas, which contrasts with the broader, systemic nature of fibromyalgia. Thus, the defining feature of pain and tenderness present throughout the body without joint inflammation makes fibromyalgia the correct answer.
