Extended oligoarthritis

A group of young people camping

Extended oligoarthritis is a type of juvenile idiopathic arthritis (JIA). This form of JIA starts as oligoarthritis in the first 6 months, which is usually a mild form of arthritis, and then causes problems with many joints (5 or more) after that.

This type of JIA can cause damage to your joints and your doctor may suggest early treatment with drugs like methotrexate to keep this damage to a minimum.

You can read more about extended oligoarthritis on our JIA pages.
