The human body has 360 joints. Joints form the connections between bones and provide support and help you move. Any damage to the joints from disease or injury can interfere with your movement and cause a lot of pain. As we age, our joints are the first to feel symptoms - creaking, stiffness and pain. Many different conditions can lead to painful joints, including osteoarthritis, rheumatoid arthritis, gout, strains, sprains and other injuries.
