What common symptom is seen in Polymyositis?

Muscle weakness in the hips and shoulders is a hallmark symptom of polymyositis. This condition is characterized by inflammation of the muscles, leading to progressive weakness that typically affects the proximal muscles, which are those closest to the trunk of the body. Patients often experience difficulty in performing daily activities such as climbing stairs, lifting objects, or reaching overhead due to this specific muscle weakness.

The other options present symptoms that are not primarily associated with polymyositis. Swelling in the joints is more commonly seen in conditions like rheumatoid arthritis. Pain in the lower back is often related to conditions affecting the spine or lumbar region, rather than muscle inflammation. Lastly, color changes in fingers and toes are typically related to conditions such as Raynaud's phenomenon, which is not a characteristic symptom of polymyositis. Thus, the specific nature of muscle weakness in the hips and shoulders sets it apart as the most accurate answer in the context of polymyositis.
