What is characterized by the inflammation of joints?

Arthritis is characterized by the inflammation of the joints, which leads to pain, swelling, stiffness, and decreased range of motion. This condition can affect one or multiple joints and can vary in severity. There are many types of arthritis, with osteoarthritis and rheumatoid arthritis being two of the most common. The inflammation results from an immune response, wear and tear on the joints, or other underlying health issues, ultimately contributing to the symptoms and overall functional impairment of the affected individual. Understanding arthritis is crucial in distinguishing it from other conditions that may involve soft tissue, muscles, or bone density, but do not specifically involve joint inflammation.
