Hi KSandy
So sorry your daughter has been struggling with this flare up of symptoms.
I can only answer re TS tics specifically:
Yes, we learned to identify what causes flares, but sometimes the mystery remains.....
Flare triggers are very varied and can either be common to many, or unique to the individual. Another reason why keeping a journal is so very helpful. Similarly the duration of a flare is hard to predict.
We would always have our "go to" when a flare started. Try to identify the trigger and also use whatever methods have worked before to slow the flare. In our case certain supplements, epsom salts(magnesium sulfate) baths, other detox methods and very specific acupuncture were usually most helpful. Anti-inflammatory supplements like boswellia, curcumin, Omega3 etc helped and I know for many PANDAS patients-ibuprofen can help too (cvs sells 200mg dye free!)
Flares usually mean "something" in the environment or internal has triggered the immune system from our experience-and so identifying and eliminating that "something" and then doing whatever helps to reduce that ramped up immune system & inflammatory response
Hope that may offer some helpful tips
