The CDC reports this year's flu shot may not protect against a strain of influenza that's hitting the U.S.
Q. Does this mean the flu shot is useless?
Not at all. Although this year's flu vaccine doesn't match two of the three main types of flu strains now in circulation, people who did get a flu shot and catch the flu get a much milder disease.

In addition, if you have a health condition such as asthma, chronic bronchitis, or emphysema, you might experience several weeks of respiratory symptoms long after the cold is over. Let’s look at some of the common cold complications that occur.
Colds and Sinus Infections (Sinusitis)
A sinus infection is an inflammation of the mucus membranes that line the sinus cavities. This inflammation causes the mucus glands in the sinuses to secrete more mucus. When the passages in your sinuses become blocked, pressure develops and your nose may feel plugged. If your cold lingers for more than a week and you begin to have pain in the sinus area, headache, upper tooth pain, nasal obstruction, cough, thick yellow or green nasal drainage, call your doctor. You may have a sinus infection.
If you have asthma, a cold can make you feel congested and make you cough as you try to expel mucus from the throat or lungs. You might have a dry cough and wheeze initially with an asthma attack. Then you may experience feelings of breathlessness, chest tightness, and coughing. If you notice a worsening of your asthma symptoms, follow your asthma action plan. If you continue to get worse, call your doctor or get medical treatment immediately.
