He has alot of different symptoms--gut issues, allergies, ocd, tics, and leg pains. His ocd has gotten quite a bit better, allergies a little better, tics about the same, emotional issues much better, cognition better--able to focus in school better. I don't know if I can put a percentage on it, but after switching to azithromycin and bactrim, plus ivig, he is doing so much better than last year at this time. One of the major improvements is that he is able to play by himself again and entertain himself (he is our only child and demands alot of attention). Anyway, it all seems to be helping.
