If there is any way you can get insurance, you should do it now. Good description of the ways rsd spread have already been mentioned below and i agree totally.
The throat i am not sure of, but i have read of so many things rsd is responsible for, that i would not be surpirsed. Also, it surpresses the immune system and so it could be some sort of infection.
Good luck to you and let me know how you make out.
