Hi gingermom
Hopefully someone with more PANS knowledge stops by- but I just wanted to welcome you, and say that I am thankful there was that relief from the ibuprofen. fyi CVS has their own brand 200mg dye-free ibuprofen (we have always avoided food dyes)
My son dealt with Tourette along with intense OCD, and we do suspect a PANS component, but this was many years ago-but we also used a natural anti-inflammatory by NOW called Boswellia extract that has Boswellia + Curcumin. Our Integrative MD also suggested Olive Leaf Extract as a natural antibiotic, and you will find other posts about it -sometimes abbreviated OLE -
I do hope you find the info you need to help your daughter.
