I had been trying the hydrogen peroxide for about three weeks, and my sinusitis just got worse and worse, until I've had to be off work for a whole week. I've never been that bad before, never had to have a day off work before. Until I went to the doctors 2 days ago, I hadn't even done my dishes for nearly a week! He gave me a spray and some antihistames and they worked immediately. It's sooo good at the moment to just be able to breathe and to go about normal daily life.
I don't think I got the method of using the HP wrong - it is proving difficult here in New Zealand to get a nasal sprayer - I have spent a lot of money buying different brands to get the bottle to use to spray - they have all proved to be sealed, so instead I used an eye-dropper and started with a 5O/5O water/3% HP and then went to a 3:1 ratio - (1%}. I was also using NeilMed saline irrigation once or twice a day. The symptoms just got worse and worse until I finally developed a polyp.
I may have found a way to get a spray bottle, so when I get that, I will try the HP again - more diluted. I will also try the GSE. I will keep people posted, and would appreciate feedback.
