Re: Chronic sinus problems.
They do say that when you reach the end of your rope, you just have to tie a knot and hang in there. If you have a sinus condition like a deviated septum it is usually best to get the nose corrected because the nose structure kinda determines how often you are likely to get a sinus infection.
If antibiotics are not doing it for you then you should talk to your doctor about alternative ways of treating your sinusitis. I don't know how your country works but if you have more than 4 infections a year then you can be granted surgery help by some public hospital.
