Only had NK function (13 LU) measured once during CFS diagnosis back in September. All my WBC counts have been completely normal so far on Valcyte (knock on wood

)
A month or so before I got the sudden flu illness in January I started having a chronic sinus infection and every morning when I blew my nose there was dark green snot indicative of an infection
even though I didn't feel sick at all! It was really weird.
Something definitely was getting screwed up with my immune system leading up to the fall, and the sinus infection continued with green snot every morning since January until maybe a couple weeks ago. As I've started to feel better on my aggressive treatment and supplements it seems to have gone away.
Now as you know by my posts the way I'm treating myself I wouldn't be able to tell you what is making what go away because I'm doing so much at once. Dr. Teitelbaum says that Candida overgrowth gives you chronic sinus infections or sinusitis so treating that will make it go away. I have been treating Candida along with everything else but would never be able to tell you what drug or supplement I am swallowing is fixing what ;-)
