Started On December 6th With Sore Throat And Hoarse Voice.

Started on December 6th with sore throat and hoarse voice. December 9th went to doc for continued previous symptoms and ear pain. Got 875 mg Amoxicillin b.i.d. Got worse next day! Tired, voice a lot more hoarse, not sleeping, stabbing ear pain. Tried to wait for Amoxicillin to 'kick in'. Started with low grade fever on Friday (99.6) Gone in a.m. but always came back by night. Fever continued through weekend. Called doctor's office on Monday - December 15th. Told me my symptoms were now Influenza. (did not see doctor) I continue with headache off and on throughout the day, ear pain (stabbing), fever on and off (low grade). How long does influenza last. Something I can do to speed this up?
