Sinusitis
"I&#039;m on day 4 of Zpack. Started out on Doxycycline. Took it for 2 days and had horrible side effects. Replaced with 5 day Zpack. I have had some stomach pain. It starts about 2 hours after I take it and lasts for about 2 hours. I started taking Culturelle prior to the Zpack. I think that has helped keep some of the tummy troubles at bay. I feel a lot better. I&#039;ve been sick with sinus infection for 22 days. The only issue I am having now is pain and tenderness in the bridge of my nose. I have 1 more day on Zpack. Not sure if it&#039;s going to help my nose."
