Hi Shelly, I've been out of town for a while, I'm so glad they are finally getting to the bottom of this. My sinusitis was caused by back to back infections. My ENT told me this because I have no real severe allergies. You are absolutely right - all the repeated infections are caused because the initial infection was never treated long enough to get rid of it. My concern would be that now medicine alone would not be able to fix the problem. Did you find a new ENT? If the sinusitis can't be cleared with meds, make sure you get her to a new ENT. The old one was an idiot.
As for the eyes, it's all connected. Have you ever seen those 'stupid people tricks' where people snort milk and then have it come out their eyes? That's because you do have sinuses that are connected to your eye ducts. Her sinuses were just so bad that they started to affect her eyes. Same thing with her lungs (and mine).
If she isn't improving in a few days, you need to call and have her antibiotics changed. I had to do that a couple of times. Once when I was put on Kenex(?) it did nothing for me. Apparently it only works on gram negative bugs and mine is gram positive (or visa versa). I'm on Levaquin (again) now and I'm staying until surgery. I told my ENT that I'm not going off again until he drills some holes - I'm over it. Also, I discovered that taking sudaphed 3 x a day and some guaifenisen (sp), an expectorant, twice a day (morning and before bed) and it has really helped me with the congestion. I'd ask about how much was safe to give Melanie and give it shot.
P.S. My first idiot ENT told me decongestants wouldn't help me, he was wrong, food for thought.
