Get a second opinion: It is difficult to tell for sure what you daughter has, but obviously she is having pain and needs treatment. +ana only does not mean much--some healthy folks have +ana test. Lyme disease can cause joint pain. Follow this link to read about jra--http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0001487/ i suggest getting a second opinion if you are not satisfied. Good luck.

Joint pain only: There is no blood test that can diagnose juvenile idiopathic arthritis. A positive ANA means nothing for the diagnosis of jia. Child must have joint swelling on exam or active synovitis on an MRI of the joint that must be done with IV contrast (mri without contrast cannot detect active arthritis unless it is advanced). Kids with suspected jia should be evaluated by a pediatric rheumatologist.
