Hi I am hoping I'm not alone here. My 5 year old daughter has recently been diagnosed as having JIA after 4 years of arguing with doctors. November last year she has a major flare up which caused her to be hospitalised for just over a week. They run standard tests on muscle function and her joints etc and said it all seemed ok but they suspected arthritis in joints. Almost a year on and having seen her rheumatologist recently have now been told that yes she has Jia but her muscles have become profoundly weak throughout her body please help is this normal?
