Well, we still do not know. All we know at this time is; according to the Pediatrician, all test results are negative. Even those these tests were negative and my daughter's pediatrician thinks there is a possibility what she had was viral induced arthritis; it is still recommended for Chels to see the Rheumatologist.
The Rheumatologist has stated that she wants to see Chels this coming Thursday. With my daughter's history of Hashimoto's, apparently there could be something still going on. We will see, but so far so good and Chels is doing better.
Thanks for all of the well wishes and prayers!
