Maddie is having a flair-up. Both knees are affected this time. She is preparing for the ballet Cecchetti exams next month so this has not come at a great time, not that it's ever a good time for an arthritis flair. I'd rather be in pain than watch her suffer. It's almost unbearable watching your child deal hurting. She's got a happy attitude though and is so very graceful as she deals with another setback.
Maddie and I both have HLA-B27 arthritis but hers manifests so differently from mine, as most juvenile arthritis does. Maddie has periodic flairs that show up without rhyme or reason. They may last a few days or a few weeks, then she is symptom free for weeks or months. Mine stays with me every hour of every day.
