I have what I thought was sinus infection and have taken allergy meds and others such as Allegra D and Claritin D, and also have taken 2 rounds of antibiotics, specifically amoxicillin and leviquin. I just finished this treatment and still have sinus congestion, but not a lot of drainage. I seem to have trouble with sensitivity that is made worse when I wear my eye glasses for reading, which I do a large part of the day using a computer. And I also have pressure mostly on my right side above my eye. It really throws me off my game.
