Marsha, I really like Curezone - a kind of aggregate site for natural remedies.
Here's some info re: sinus infections that will help:
http://curezone.com/blogs/fm.asp?i=973746Coindentally, last week I had a very very minor sinus infection. I doubled up on colloidal silver, taking approx 1/3 cup each day and it went away. Sovereign Silver has a bottle size with a glass dropper that you could use directly in the nasal cavity, if needed. That was my next strategy, but it cleared up.
The other suggestions in that link look even better than CS.
God bless you.
