I hope you feel better soon...The flu can last between 7 to 10 days....If your not feeling better in acouple days I would go back to the doctor.. Have you been drinking plenty fluids to keep well hydrated? You might be alittle dehyrdrated..
The last time I had the flu it was 7 years ago...DD & myself didn't get the flu shot this year ..DD just got over the flu..and I manged to escape it...I flip out when someone is sick.. I make it a habit of washing my hands often , not touching my eyes , nose or mouth when someone is sick around me ..So far this little trick works like a charm..
