I would say go the Naturopath or LLMD route. ID doctors, from what I have heard AND 1st hand experience, are not very helpful. My DD was followed by an ID Dr for osteomyelitis (bone infection) she got in her foot bone after stepping on something and getting 3 stitches!!! Within 24 hours!!! So pediatrician made us go to Childrens Hospital to be admitted and she was there for 2 days receiving IV antibiotics (followed by 8 weeks high dose antibiotic combos). Anyway, at her 1st follow up a week out, the arrogant rude ID Dr walks in and LITERALLLY the 1stnext question is if dd has had the flu vaccine (I I had said no in the hospital.)I She then continued to pressure me about this for 5 minutes basically having a staredown with me (& I am so not confrontational). At the next and last follow up I asked her about some labs that were out of whack and she said that it was normal for my dd and most people don t believe PANDAS exists! (
