Interesting post about vinegar for sinuses ...I have suffered for 9 years with chronic sinus and ear and throat infections. I've had dozens of antibiotic treatments and corrective surgery. One day I drank a tablespoonful of white distilled vinegar and noticed that I felt some level of relief, so I took this one step further. I took 12 ounces
of distilled water and one tablespoon of distilled white vinegar and used it to rinse my sinuses. This was painful I admit, butI was desperate after nine years and I was getting nowhere with my physicians. I did this for two weeks twice a day. Now after 10 years of pain and suffering I can tell you that I am cured . Anyone who wishes to try what I have done please be cautious as the solution stings the nose a little bit, but the pain quickly passes. While rinsing your sinuses you must have your head down the water will pass through your mouth. Never do this with your head upright as you could drown if water enters your lungs. Please talk to your physician before doing this. I was already familiar with salt water rinsing before substituting vinegar for salt.
