Arthritis is the name for many inflammatory conditions affecting the health of joints in the body, mainly in the spine, hands, hips and knees. Common arthritis symptoms include swelling, pain, stiffness and reduced joint range of motion. Whilst the various types of arthritis differ in features, one thing we do know is that inflammation is always involved and the presence of systemic inflammation can worsen symptoms. Chronic inflammation in the joints can damage cartilage, bones, tendons or ligaments, irritate nerves.
