Could juvenile rheumatoid arthritis return in the future?

Yes: Yes this condition is characterized by remissions and relapses that may be years apart.Discuss this with your doctor.

Yes, highly likely: There is no way to "outgrow" jra / jia. It can only be put into remission for periods of time from weeks to years, depending on what type of juvenile arthritis it is and how many joints were involved at the time of diagnosis.Kids with more active joints at diagnosis are more likely to flare more often when off meds. Until a cure is found, we work for remission with minimal flares of disease.
