3 weeks of swollen throat, ear popping, hoarseness, cold symptoms ( cough, tiredness, runny nose) what could this be? tried allergy meds, but to no avail

See a doctor: Three weeks of any illness without improvement or a diagnosis is sufficient to warrant professional evaluation. Sounds on the surface as if this may be due to allergies, but without testing there is no way to be sure.

See a doctor: If you are having these symptoms for three or more weeks you should see a doctor for diagnosis and treatment.
