Postnasal drip
This is a dry or often wet cough caused by mucus dripping down your throat. Postnasal drip could appear due to allergies or a simple cold. If symptoms linger for a week or longer, you better visit your doctor to rule out a sinus infection or other problem.
Asthma
A persistent and dry cough, sometimes with wheezing, in response to some triggers like animal dander, pollen, dust, exercise and other ones. This is a serious condition that requires treatment. Visit your doctor to identify your triggers and to have a prescription that will help you reduce inflammation.
