This is what happens when joints — the places where bones meet — get painful, swollen, and stiff. People with arthritis may find it painful to move their joints. Arthritis can happen when someone loses some of the flexible cushion between the bones called cartilage. You may know some older people with the condition. Kids who have arthritis may have an infection, Lyme disease, lupus, or juvenile idiopathic arthritis.
