Arthritis
Say: ar-thry-tis
This is what happens when joints — the places where bones
meet — get painful, swollen, and stiff. Someone with arthritis may find it painful
to move his joints. Arthritis may occur when a person has lost 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
rheumatoid arthritis.
