Hi! Thank you for your question. Flu
and other upper respiratory viral infections typically last only for a week. I would recommend that you go see a family physician so that he/she can examine you more closely to find out what really is going on. It is possible that you now have a bacterial infection that was superimposed on your viral one so a course of prescribed antibiotics may be necessary to cure your symptoms. I hope you feel better soon! Please don't hesitate to contact me again if you have any further questions.
