HI...where to start....well I've had a cold for like 3 weeks....this weekend I awoke both mornings and blew nose and it was yellowish first thing in the mornings, then it goes back to clear....so I went to an promed place Sunday and was put on an antibiotic(cipro 250 mg twice a day) and was told I had a lot of fluid behind ears.....Today I went to a ear nose and throat doctor....no fluid....he looked really well at everything....saw drainage but no indication of an infection....... I only had like 2 doses of cipro....could it have cleared up that fast? I'm not even sure I had an infection.......no fever....just the 2 mornings with it being yellow first thing then back to clear.......anyway...ENT doctor left it to me whether to stay on antibiotic or not and i'm thinking it has to be viral since I never ran a fever? I dunno.....what's your thoughts please...thank you paula
