Hi Kimmie...
I know this is a frightening time... facial swelling is not fun...
Please rule out any other possible issues before ruling it as RSD swelling...
(if you haven't already that is...) Could also be sinus related or dental related....
My face swells off and on but it also turns bright red and ice cold when it does this.... mine happens on one side or the other... never swells both sides at the same time.
I wish you well!!!!

Abbie
