Hi MAJ,
I am also in Columbus and have a wonderful pediatrician helping my daughter with PANDAS here. We were having the same issues of back to back episodes as antibiotic rounds were finished. Her Dr. then decided to test everyone in the household to identify one of us as a strep carrier....which ended up being me. Once I started to be treated the same time as my daughter we saw great improvement. If you would like the contact information for her pediatrician in our area please let me know.
Thanks and good luck!
