For decades, I was constantly getting sinus infections. I would take antibiotics, which got rid of the infection, but would just get another infection. I had had sinus surgery, but that didn't seem to help.
Back in 2001, about a week after just getting over another damn sinus infection, I felt that my sinus were, once again, getting infected. Stupidly, out of frustration, I put my head down and flooded my sinuses with diluted Hydrogen Peroxide. I didn't dilute the Peroxide enough, and it burned the hell out of my sinuses and left me much worse for three days.
I thought that I had really messed up this time.
After three days, my sinuses felt better than they had felt in a long time. The sinus flooding with Peroxide actually worked! It almost killed me,
but it worked! I've gone many years without another sinus infection, and I never have to do any more sinus floodings with Peroxide, or irrigate, or do anything to my sinuses in order to avoid sinus infections. I can honestly say that I am totally sinus-infection free!
Anyways...... I am not suggesting that anyone try something similar, unless under a doctor's care. But if you are interested in seeing what I did, in order to get some ideas, I documented what I did in the thread: New 'upside down sinus flooding' documentation

Best of luck finding a solution to your sinus infection problems!
