Overview

Arthritis that develops in children is called childhood arthritis (or juvenile arthritis).A1

Childhood arthritis begins when the immune system becomes overactive, leading to joint and body swelling.

Childhood arthritis can cause pain, loss of motion, and permanent damage in the joints. 

• This can make it hard for a child to walk, play, or dress themselves.
• It can also result in disability.

Signs and symptoms

The symptoms of childhood arthritis may be different for every child. They can include:

• Joint pain.
• Swelling.
• Fever.
• Stiffness.
• Rash.
• Feeling tired.
• Loss of appetite.

There may be times when symptoms get worse, known as “flares.” There may also be times when symptoms get better, known as “remission.”

Causes

The causes of childhood arthritis are not known.

• Have a heart condition.
• Have overweight.
• Are not physically active.
• Live with people who smoke.

Diagnosis

Symptoms of childhood arthritis might seem like other illnesses and injuries. 

A pediatric rheumatologist, who specializes in childhood arthritis, can help figure out the right diagnosis.

These doctors can diagnose childhood arthritis by doing: 

• A physical exam.
• X-rays.
• Lab tests.
• A review of health history.

Management

To help manage arthritis, doctors may prescribe medicine and advise children to be physically active.

This may include exercises like those recommended by the Arthritis Foundation:

• Water exercises (like shoulder shrugs and ankle circles).
• Swimming.
• Bicycling.
• Tai chi.
• Yoga.

Treatment

There’s no cure for childhood arthritis. But there are ways to treat it. Doctors can work with children and their parents or caregivers to develop a treatment plan. 

Transitioning patients to adult care

Some children’s arthritis improves as they age. Others may continue to have symptoms into adulthood. 

Moving from child to adult care can be hard for those with arthritis. It can also be hard for their parents, caregivers, and health care providers.

The Arthritis Foundation has transition resources on how to:

• Make appointments.
• Understand health insurance.
• Adjust to working or education beyond high school.
