Dear Hippimom,
Wow, what a thing to happen. I know we all feel that it's better us than the ones we love...so I know it is heartbreaking. But I know from personal experience with kids who have JRA, they are more resilient & handle it better than most adults!
Ok, dependng on the state you live you really should contact the Juvenile Arthritis Family Network ran out of the Arthritis Foundation. They hold conferences & have help lines for parents, siblings & children with arthritic & rheumatic disease.
If it turns out to be a definitive DX of JRA for your son, there are FANTASTIC summer camps for kids who have JRA! And also mini-events throughout the year. No better way for him to learn, connect & make sense of it all.
From the symptoms you gave & the bloodwrok he had done, it certainly does sound like RA to me.
Keep up with the PT, that will help the most with range of motion and strength. The PT can also be most useful in explaining how he should pace himself throughout the day, start to learn how to pay attention to when his "breaking" point is with activity. The importance of rest, etc.... and also can explain medications & how they work. The PCP can do this too.
Age 8 is a very receptive time in life. They want to gain independence, so no better time for teaching & learning!
NSAIDs are the 1st line of TX for JRA and corticosteroids when necessary (they are avoided due to growth inhibition like you were worried about). The 2nd step would to add MTX to the NSAIDs.
Now's the time to let him take care of his own body! Encourage him to express his concerns & questions.
Offer remedies that he can do himself at any time such as: moist heat application to joints; warm baths; swimming; paraffin dips for hands and feet; ice packs; the importance of mantaining GOOD posture while sitting & walking; get a firm mattress; not to cross legs like a pretzel while sitting or watching TV! LOL; and to wear sunglasses to protect his eyes. Photophobia from iridocyclitis can occur so yearly eye exams are a MUST!
The childs natural instinct to move & play will keep @ bay a lot of damage and complications...so this is a good thing!
I would absolutely ask the MD straight out what is going on in terms of diagnoses. In fact, those are YOUR medical records! YOU OWN THEM! Get all copies of them.
Could be that the rheummy needed to put down JRA as a DX for approval of bloodwork and meds. It is much different in adolescants regarding diagnoses codes for billing & insurance and such. But you need to be in the know.
The doc might not have said anything because he/she might be in the stages of ruling things out still...if you do like the doc; do give the benefit of the doubt. Doctors are a lot more careful and on top of things when it comes to children!
You're going to be OK!
With love,
Erin
