His first year of treatment and prophylaxis for strep had quite a few flares. He would reach 80-85% recovery at best. I considered a flare to be an increase in symptoms, mostly anxiety and OCD, never as bad as the initial "fall of the cliff" but some were pretty close. The "blip" I have seen previously described as only a mild increase and in our DS's case, it was only 2 days and we could pretty much talk him through most of it. I don't believe his true recovery started until there was further testing which revealed an active mycoplasma infection (for how long who knows) and chronic sinus infections - this was over a year into treatment with azithromycin for flares and Keflex for prophylaxis for strep. Antibiotics for sinus/mycoplasma started (biaxin was the only thing to rid him of OCD - the other antibiotics and CBT made it manageable except when in a flare, biaxin got rid of it). I am holding my breath this allergy season though since that is a piece of his puzzle and has caused flares in the past. Our biggest relief from flares prior to the mycoplasma discovery, was when our entire house was treated for strep (and retested after), including the cat - he wasn't retested though:-). Then he was free from flares except the "blip". It's getting late, I hope this makes sense.
