sinusitis
"I suffer from sinus/ear infections at least 2-3 times a year.  My doctor first prescribed Augmentin but this only made my symptoms worse.  After feeling miserable for 2 weeks my doctor then prescribed Avelox.  Besides the jitteryness, rapid heartrate, and anxiousness, it worked wonders.  This medicine cures symptoms quickly, but does have side effects.  Everyone is different so be aware of your body and let your doctor know if you're uncomfortable."
