My Symptoms Are As Follows: Chest And Sinus Congestion, Rough

My Symptoms are as follows: Chest and sinus congestion, rough cough, headache from the top of my nose to the top of my head, shortness of breath during regular activities, coughing up at times large amounts of mucus, and a sore and swollen tongue. I have had these same symptoms for approximately 3 weeks now and no signs of improvement with any over the counter medicine. Is this something that i just need to tough it out or is it recommended to see a physician?
