My 9 yo daughter has swollen finger joints in one hand and has elevated aso levels, could this be from scarlet fever 4 yrs ago?

Maybe: Elevated aso levels indicate a past strep infection....Just not exactly when. It is important to have her evaluated to see if it is something acute or if it could be related to strep.In the cases I have seen of rheumatic problems after strep the patients did not remember having a strep infection. If her scarlet fever was treated then this may not be related.

Integrative therapy: In this case of swollen joints one hand, it is important to be evaluated by a physician. I also refer often to traditional chinese medicine practitioners for many conditions (even one like this) as it helps immensely and can augment traditional treatment as well.

Pauciarticular?: Swollen joints are never normal in a 9 yo. Elevated aso suggests rheumatic joint disease. But there are many other tests are necessary to evaluate her small joint arthritis. She should see a pediatric rheumatologist. See http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0001487/ for further information.
