sinusitis
"I have been so blessed to start using Levaquin.  I have been sick for 1 months so far.  I thought it was a cold, but I couldn't recover. After 2 weeks I took a Z-Pak for 5 days, and my symptoms got better, and then it came back.  So, after 4 weeks of sickness, I started the Levaquin and after the first dose my ear infection that I also had at the same time was healing quickly. The second dose had me feeling so much better, that I believe this sinus infection will be gone soon. Yeah!"
