Whooping cough, also called pertussis, starts like the common cold with a runny nose or congestion, sneezing, a mild cough, fever, and sleep apnea. After one to two weeks, severe coughing can begin. Whooping cough can cause violent and rapid coughing, over and over, until the air is gone from the lungs and you are forced to inhale with a loud whooping sound. Occasionally, vomiting may also occur.  You should see your doctor immediately if you have a whooping cough.  It is important to know that many babies with whooping cough don't cough at all. Instead, it can cause them to stop breathing. Infants and children under six years should seek emergency medical care immediately.  There is a vaccination for whooping cough. Make sure you vaccinate your children against this disease. A cough and sore throat can also be symptoms of nasal infection. If your doctor suspects chronic nasal infection, also called sinusitis, she may request imaging tests including an X-ray, computed tomography (CT) scan, or magnetic resonance imaging (MRI). Other common symptoms of nasal infection are fever and headache. If you have a high fever or severe headache, you should seek medical care immediately.  You may also feel pressure in the forehead, temples, cheeks, nose, jaw, teeth, behind the eyes, or at the top of the head. Nasal infections are also accompanied by nasal stuffiness, loss of smell, nasal discharge that is typically yellowish green, or a post-nasal drip. Rare complications associated with chronic sinusitis can include blood clots, abscesses, orbital cellulitis which causes inflammation around the eyes, meningitis, and osteomyelitis, an infection that spreads to the bones of the face. Bronchitis is an inflammation and accumulation of mucus in the air passages of your lungs. This can often lead to chronic coughing and chronic obstructive pulmonary disease (COPD), regardless of whether you have acute or chronic bronchitis. It is usually caused by cold viruses, exposure to secondhand smoke, or gastroesophageal reflux disease....
