Arthritis is joint pain or joint disease that causes inflammation (pain and swelling). There are many types of arthritis, but the two most common are osteoarthritis and rheumatoid arthritis.

Osteoarthritis, usually just called “arthritis,” is much more common than rheumatoid arthritis. Wear-and-tear on the cartilage causes arthritis. Cartilage is the flexible tissue that coats the ends of bones (joints). If enough cartilage wears away, one bone rubs against another.

  • Joint pain
