I have had BMS symptoms since the RSD travelled to my head/ face/ jaw area, and I just attributed it to the RSD. It seems like just a small irritant will set RSD off in new areas for me (almost full body now)- I am not trying to scare you, but after I ran for the first time in months (and only had RSD in both hands/ arms/ shoulders) I woke up that evening and felt RSD in my feet. Just from my experience- MAYBE the thrush was enough to set the RSD off in your lips/ tongue?!

I am sending many soft hugs your way

I know what you are feeling- RSD is soooo nasty! And the face part is one of the hardest for me.
