I took Azithromycin 500MG for 3 days recently for what seemed like mild flu symptoms (sinus issues, throat issues, spitting up some mucus). After 3 days I developed a full fledge chest infection that has hung around for a few days along with a worse cough than I had prior to going to the doc. I am now spitting up more mucus and running nose. I do seem to be feeling better overall (acutually jogged 4 miles today) but after reading the posts I have to think it has caused me some delay in fully recovering....
