I've posted before about having symptoms very similar to yours and a few others. Again, mine started about the time I got giardia and c difficile toxin. I was also exposed to mold and am very sensitive to it now. Since I last posted awhile back, I've tried a sinus rinse produced since 1896. It's called Alkalol, and has all sort of herbs. I believe it's helped quite a bit. Also, I've added a few drops of povidone Iodine to salt water rinses when I use them. Albendazole got rid of giardia, mebendazole didn't help it at all, and I wish I could find some way to get rid of this sinus stuff. The drainage is now causing me coughing and chest congestion every day instead of just at times.
