Hi welcome to Health care magic forum. You had a viral infection followed by secondary bacterial infection that too lower respiratory infection, so you need to have examination by a chest physician. Some timesif you use anti histamines
you can have thick phlem, causing difficulty in breathing and expulsion of the sputum.
I advise you to consult a chest physician for diagnosis and treatment, you may need to get the CHEST XRAY, besides other routine tests for confermation.
Besides i advise you to follow some diet recommendations as avoid taking fruits, juices, ice creams, ice water, for few days till you get complete relief as these are supposed to cause allergy
and trigger the rhinitis
Wishing for a quick recovery and thanks for calling.
