Cough, chest/nose congestion, tired, blocked ears over a week. taking zyrtec, mucinex, (guaifenesin) advil. is it cold, allergies, something else?

Non specific: Not sure what the question really is, but if you are talking about upper respiratory tract or head cold symptoms due to infection versus if they are do to allergies, allergic symptoms tend to occur with exposure to kn own or suspected triggers, would not have fever, or sore throat, infections would be more likely to have fever, sore throat, no clear allergic exposure etc.
