I have been sick for over 2 weeks. The first time i went to the doctor 3 weeks ago he told me that I was just very run down and not sick. Well now for 2 weeks i have had a cough, fever, mucas draining, and very tired. If it is the flu or cold i have taken every over the counter med you could imagin to get rid of it but I am still yuk. My cough went from hard with mucas to empty and hurting, my throat is killing me, and i am still running a fever. If i go back to the doctor are they going to be able to do anything for me?
