bacterial infection
"This past Wednesday my right nostril was a little sore, figured I was a little overly aggressive with the allergy early morning blowing.  By Friday 3:30 am I woke up to stabbing pain all on the right side of my face!  Swollen and the tissue was HARD, nasal passage (where the infection started) was 3/4 closed!  Today is day 4, my face is pliable again, still a little stiff close to my right nostril, but my lips, cheeks and eyes feel great, nostril very slightly tender in comparison to Wednesday.  This Avelox works only problem I've had is dry mouth (drinking plenty of water) and a little light headed/dizzy, but I'm not driving so that's okay!"
