What is arthritis?
Here comes the geeky bit! The suffix ‘itis’ means inflammation, and arthritis simply means inflammation of the joints.
There are many different types of arthritis, but the most common is osteoarthritis. Healthy joints are covered by cartilage, a rubbery material that creates a cushion between the bones and provides a smooth surface for movement. When arthritis occurs, this cartilage breaks down, causing swelling, stiffness, movement problems and increasing pain, which steadily spreads throughout the body.
