Report DS having relapse 6 years after healing from tonsillectomy, 2 IVIGs, 1 year on abx...what's happening?!?! in PANS / PANDAS (Lyme included) Posted June 20, 2017 Thank you all so much for the responses. We are scheduling with Dr. Infante ASAP and I got an email back from Dr. Cunningham office and they concurred that even if they appear to be healed things can trigger relapses even years apart. We had no idea! My son is 12 and is in the beginnings of puberty so that was something I did not think about either as possibly impacting things.
