Since the Vicks on the bottom of the feet didn't work for treating my cold/sinus infection, I tried the hydrogen peroxide in the ears. It was really cold, and made my ears feel like I did when I was a kid and spent all day at the pool. You know, that skritchy sound in your ear and you have to shake out the water. I don't think it helped a bit, but maybe I missed the 12-24 hour window of opportunity as described in the article.
My sweet SIL suggested another home remedy of dropping a solution of baking soda, salt and warm water in your nostrils, so I tried that, too. It did seem to help, and so did a full sinus irrigation. Just hope it doesn't get worse.
