[YEA] I have had two severe sinus infection flare ups over the last two months. The post nasal drip from this infection has caused me to have SEVERE laringitis, so severe that i could not talk at all. As if my vocal cords were completely gone. I could only use sign language and even whispering hurt my throat and head. Has anyone ever had this problem? I have looked everywhere on the internet and have not found one story of laringitis caused by a sinus infection. I am using 13 drops of GSE and 1/8 tsp. of sea salt mixed in 3/4 cup warm water. i use a full eye dropper, tilt my head back and squirt it up both nostrils. Then i quickly plug my nose and put my head down between my legs. I plug one nostril and gently breath in through the other. Doing the same with the other nostril and back and forth for about 1 minute. When i first started doing this, the pressure in my sinus was almost unbearable. But now on my 5th day of doing this about 3-5 times a day, the pressure is gone. I still have laringitis but it is not lasting as long as my first bout with this infection. I am also starting the ACV drink. If anyone has had this Laringitis trouble, please let me know. I was completely mute for 3 days!!!
