The most common symptoms of all forms of juvenile rheumatoid arthritis (JRA) include:
- Joint pain and swelling that may come and go but is most often persistent. Symptoms must last for 6 weeks before a diagnosis of JRA can be made.
- Joint stiffness that lasts longer than 1 hour in the morning.
- Irritability, refusal to walk, or protection or guarding of a joint. You might notice your child limping or avoiding the use of a certain joint.
- Often unpredictable changes in symptoms, from periods with no symptoms (remission) to flare-ups.
Additional symptoms vary depending on which type of JRA a child has:1, 2
