What can cause a chronic cough for 7 months?

Answer 1

Common causes of cough include infections (eg colds and flu), Asthma, smoking and acid reflux. Since coughing causes irritation to the airways, which can itself cause coughing, a dry cough can persist even when its original cause has gone.

There is little evidence that cough suppressant medications are any more effective than placebo, but if you find that taking a medicine helps, you can buy them from a pharmacist. Other self-care measures include steam inhalation (from a bowl or from hot drinks), and sucking sweets. If you have a dry cough (ie one that is not bringing up mucus), you should try to resist the urge to cough, to help stop the cycle of cough-irritation-cough.

Answer 2

Whooping cough, bacterial or viral infection, post-nasal drip, asthma, foreign body, tuberculosis, esophageal reflux, and medication side effects are just a few examples of chronic cough causes.

You should see your doctor.

Answer 3

It may be an allergy and should be checked out. Be prepared for a long search for the answer.
