When cold or flu symptoms last an abnormally long time or are more severe than expected medical attention may be required. It may be allergies, sinusitis, or some other secondary infection that is causing your cold to last longer than two weeks. If you experience symptoms such as stabbing pains in the chest, sputum that is colored, fever, or shortness of breath, you may have pneumonia. As a cold and flu may be difficult to tell apart based on symptoms alone it is important to seek medical care when in doubt. Cold and flu treatment is available at Q Day Walk-In Clinic.
