Thanks for writing your query to us.
Your symptoms suggest that you have developed chest congestion. Try taking steam inhalation twice a day that will loosen up the cough
& than you will be able to bring out the cough. Usually a cough & cold
responds to any form of treatment within 1 week or atleast shows signs of improvement in 1 weeks period. If your symptoms are still the same , or are getting aggrevated than i would suggest that you should visit a physician so that he can examine you . Xray of chest would also help to come to a conclusion of non responding cough.
Wish you good health.
