Head Cold Help!!!

Yeah, I usually use one with my allergies, but my physician does not like me to use it when I get head colds, something about possibly infecting my brain with germs from my nose.  I looked up what he was talking about, ameobas, and people have actually died from it??? I did not know that.  I will still use it with my allergies, but not when I'm sick.

I called the office and they said the theraflu stuff is okay as long as it doesn't have NSAIDS. 

Thanks for all the suggestions everyone, and have a safe and happy New Years!
