Hi. About 4 weeks ago, I started having frequent headaches. I had facial pain in my cheeks and forehead and I felt that Advil wasn t helping any more. I saw my doctor who diagnosed it as sinus infection and put me on Zpack. I felt better after taking them, but when they were finished the pounding headache came back. This time, he put me on Cephtin 500, twice a day for 10 days. I felt better and flew to LA, where on the last day of my antibiotics the pounding headache came back. I called my ENT who prescribed Pathanase, Nasanex, and Sudafed. I have been on those for the past week. I m back in NY and now I have thick, clear mucus and cough. I don t know if my sinus infection is gone yet. I m still suffering and don t know what to do. Please advise! Thank you!
