sinusitis
"Biaxin (or the generic) has always worked WONDERS for me in treating chronic sinusitis or sinus infection (also concurrent ear infection).  It smacks it right out of you the 1st time, you don't wind up at the doctors again after taking something less effective. I ask for it by name (am allergic to penicillin and sulphur, so neither of those are ever an option for me)."
