What is a common symptom of arthritis that can be alleviated by exercise?

Pain and stiffness in joints is a common symptom of arthritis that can be alleviated by exercise. Engaging in regular physical activity helps improve circulation, strengthen the muscles around the joints, and increase flexibility. This can lead to reduced stiffness and discomfort felt in the affected areas. Exercise also promotes the secretion of endorphins, which are natural pain relievers, potentially diminishing the perception of pain.

The other options, while related to arthritis, do not accurately capture the symptoms that exercise can help alleviate. While increased swelling in joints and decreased range of motion can be associated with arthritis, these symptoms may require different management strategies and may not see immediate relief from exercise. Skin rashes are typically not related to joint pain or stiffness and could indicate different medical conditions unrelated to arthritis symptoms. Thus, focusing on the symptom of pain and stiffness highlights the therapeutic benefits of exercise for individuals suffering from arthritis.
