I suffered with almost the same type of cold over Christmas and New Year. I typically have the throat cold that you described because I still have my tonsils and they always get inflamed. In the last couple of years I upgraded to sinus infections, which I never had before. Well, now I always get the sinus problems first.
I haven't slept through the night for about five nights, as you describe. The phlegm from the sinuses drained into my throat and that made me cough my lungs out. I took a dewormer, oil of oregano, two anti-viral tinctures and the super tonic to blast out the mucus and it took me a week to do so.
I discovered something miraculous for stuffed nose: i swabbed my nostrils with castor oil because I couldn't stand the dry membranes anymore and the nose would open up! I kept doing it after every time i blew my nose, always using a clean q-tip and it was magic.
I read somewhere that congested sinuses are related to a congested liver. Isn't everything a reflection of a congested liver?
