See, that's the thing, I have been fighting this sinus thing for going on six months now, and I have made good progress and got it to the point where my sinuses are not congested with mucus anymore. I hardly ever have to blow my nose now, and on the rare occasions that I do have to blow it, the mucus is always clear or a tiny bit white and no longer yellow or green(i.e., major infection is gone).
The only remaining problem I have, which I've read of many others having as well, is that my sinuses are swollen most of the time now and my ears are always clogged up. According to a few things I've seen, the swelling in the sinuses is the body's reaction to the fungus still embedded in the sinuses, and that swelling then prevents your ears from draining properly, which results in the clogged ears.
So I have got my water kefir in my nasal spray bottle and have started today. Wish me luck.
