Hello,
I can understand your concern. As you were
smoking for a long time, cilia which are hair-like projections in the windpipe that move and throw debris and small harmful particulate matter out of the system, had degenerated due to harmful chemicals present in the smoke.
Now, as you have quit smoking, the cilia are regenerating which is causing irritation in the throat and
constant coughing. This coughing is a sign of healing and it is good. It will automatically disappear in 6-8 weeks.
However, if you are having
lymph node swelling, then there might be presence of infection in the throat or nearby area. For that reason, I would advise you to visit an
ENT specialist for clinical examination of the lymph node and further investigations if needed. If infection is present, you will have to do an antibiotic course.
I hope this information helps you. Thank you for choosing HealthcareMagic. Take care.
Best,
Dr. Viraj Shah
