What is a common symptom of osteoarthritis?

Joint pain is a hallmark symptom of osteoarthritis, which is a degenerative joint disease primarily affecting the cartilage in the joints. In osteoarthritis, the cartilage breaks down, leading to pain, swelling, and decreased mobility in affected joints. This pain often worsens with activity and improves with rest, making it a defining characteristic of the condition.

The other symptoms listed, such as low energy, skin rash, and nausea, are not typically associated with osteoarthritis. While individuals suffering from chronic pain may experience low energy due to the impact of pain on their daily life, it is not a direct symptom of the disease itself. Skin rash is usually related to inflammatory or allergic conditions, and nausea can stem from various other health issues. Therefore, joint pain stands out as the most relevant and common symptom of osteoarthritis.
