Should i go see a doctor? please help.?

I've been sick for about a week and a half now with some kind of cold. My ear keeps poping (maybe i blew my nose too hard??) my head has been POUNDING for two days im continuously coughing and my chest and nose are congested. i have taken theraflu, niquil, tylenol cough, honey and lime, and vitamin c and nothing seems to work. is this enough for me to visit a doctor? I don't want to make an appointment and show up and have him tell me everything that i already know. help?
