MD's are more aware that Antibiotics for sinus infections are not as effective as once believed.
I was so sick one MD put me on fluconase. My MD told me that would increase the sinus fungal infection and make me sicker I guess the previous MD apparently lacked that vital piece of info.
I believe hydrogen peroxide is good, but the best way to get rid of sinus infection is get with an ND and begin the ozone injection into the sinuses it is pretty painless the needles are small.
The other way is buy a ozone generator we have an excellent ozone generator and I sit by in the evening and ( portable you can move into any room ) OZONE is fast, natural, effective way to get rid of sinus infections once and for all! My holistic dentist has a snazy ozone machine in his surgerical room. Doctor/dentist that are in the know are using it
