I am 60 years old went to the pcp today with fever 100.6, sore throat, white stuff on my tonsils and a terrible cough. He did a strep test that was negative and a script for Bromfed DM syrup. It is not helping the cough at all. Did I waste my money, $29, for the medicine? What can I do to calm this cough. I ve went through over 1/2 box of tissue coughing up gunk from my lungs. My head, throat and chest hurt.
