I had a sinus infection in early February and took a full course of ZPak. On March 1st I had a sudden onset of a chest infection and am on the 2nd course of another antibiotic that I can t remember the name, its a small orange pill. My cough is not going away and now the right side of my head (sinus, lymph nodes, and my lungs) still bother me. The cough, when it happens is very intense and I lose my breath, the first week of these symptoms a month ago I coughed so hard I blacked out on my feet? Should I go to Urgent Care or wait a week to see my primary care Dr?
