Which condition involves pain in muscles and soft tissues rather than joints?

• A. Osteoarthritis.
• B. Tendinitis.
• C. Fibromyalgia.
• D. Bursitis.

Answer: (C)

Fibromyalgia fits the description because it involves pain in muscles and soft tissues rather than in the joints themselves. The pain tends to be widespread and is often accompanied by fatigue, sleep problems, and cognitive symptoms, with normal joint findings and typically normal inflammatory tests. In contrast, conditions like osteoarthritis cause pain primarily from the joints themselves due to cartilage wear; tendinitis is pain from inflammation of a tendon near a joint; and bursitis is inflammation of the bursa around a joint.
