He's been checked for Celiac. He is on his 3rd course of antibiotics this summer for a sinus infection. I'm wondering if he doesn't even have a sinus infection. It seems like he has some kind of inflammation that just travels around his body...eyes, sinuses, bladder, bowels. Nothing seems to help and, just like that, it is gone. I'm going to ask the doctor about vasculitis. It definitely had a strep connection, at least in the beginning, but he hasn't had any strep infections in over a year. Right now he is taking Florastor and antibiotics. Just did 4 days of prednisone.
