I contracted the flu on December 28, fever,chills,headache,bad cough with lots of greenish phlegm. It took almost 2 full weeks and a prescription of cerufoxime to get rid of the cough. I had constant bouts of racing pounding heart during this period which I thought was due to fever, The racing pounding heart has not gone away. It gets so bad I can hear it pounding in my ears. I have had chest xrays, ekg and blood tests all normal.
