Hello. Welcome to hcm.
Recurrent cough might be chronic bronchitis
I advice you to undergo ECHO, PFT, XRAY chest first. Depending on finding,a diagnosis can be made. Mucus secretions can be sent to lab for examination. Chronic cough
can damage lungs and have effect on heart and brain. So the earlier the better.
Dring warm water,avoid cold
by wearing warm clothes.
You should be started on antibiotics and bronchodilators and mucolytics once the tests are done.
All the best
