Browsing through the posts seems to indicate success in eradicating "internalization" of strep with a "cocktail" of antibiotics (sometimes coupled with the removal of tonsils). Can anybody confirm this approach? My son has had at least three repeating bouts of strep with PANDAS symptoms. Amoxicillin was prescribed the first two times, and the last time Cefdinir (4 weeks ago). But his symptoms seem to be coming back. I am wondering if a cocktail of Azithromycin and another like Cephalexin has worked.
