Final answer:
Polymyalgia is the term for pain in many muscles, typically associated with conditions like polymyalgia rheumatica, whereas myositis refers to the inflammation of the muscles. Treatment options for musculoskeletal disorders often include the PRICE method and NSAIDs.
Step-by-step explanation:
The pain of many muscles can be referred to as polymyalgia. Polymyalgia and myositis are both musculoskeletal conditions but have different implications. Polymyalgia is a term for pain from multiple muscles, often associated with conditions like polymyalgia rheumatica, which causes muscle pain and stiffness, and is generally seen in older adults. On the other hand, myositis is the inflammation of muscle tissues themselves, which can be due to infection, injury, certain drugs, or autoimmune conditions.
Musculoskeletal disorders, like muscle strain, tendinitis, and carpal tunnel syndrome, involve injury to muscles or tendons due to biomechanical stresses and can be caused by overexertion, repetitive motions, or maintaining awkward positions for extended periods. These can be treated often with a combination of protection, rest, ice, compression, and elevation (PRICE), and medications like NSAIDs for pain and inflammation. Injury or disease in the musculoskeletal system, such as arthritis, can be very debilitating and impair mobility. In severe cases, joint replacement surgery may be necessary.
