Final answer:
Joint pain and swelling are the most common musculoskeletal symptoms of sarcoidosis due to inflammation. Although other symptoms like muscle weakness, bone fractures, and tendon inflammation are possible, joint pain and swelling are most closely associated with musculoskeletal manifestations of the condition.
Step-by-step explanation:
The musculoskeletal symptoms of sarcoidosis can include a variety of manifestations. While not all those listed are common for sarcoidosis, joint pain and swelling are often reported. These symptoms are related to the inflammation that sarcoidosis can cause in various tissues of the body. Muscle weakness, while possible, is less specifically tied to sarcoidosis and more to musculoskeletal disorders broadly. Bone fractures are not typically a direct symptom of sarcoidosis unless related to underlying bone disease. Tendon inflammation, similar to arthritis, could also plausibly be connected to sarcoidosis due to systemic inflammation.
Rheumatologists are specialists who treat musculoskeletal diseases and would be key in managing sarcoidosis when it presents with joint-related symptoms. They would consider the full spectrum of symptoms and might assess for rheumatoid arthritis, osteoarthritis, or other similar conditions that affect the musculoskeletal system. For osteoarthritis, diagnosis is often based on signs such as joint deformity, pain, and stiffness, while rheumatoid arthritis can also cause lung fibrosis and vasculitis.
Therefore, the correct answer would be primarily (A) Joint pain and swelling, with the understanding that sarcoidosis can involve a broad spectrum of other symptoms that may affect the musculoskeletal system. Tendon inflammation could also be included due to the inflammatory nature of sarcoidosis.
