Hi, Thanks for using HCM.
Since all your investigations were normal and you dont have symptoms of cancer, no need to worry on that. The cause for irritation may be your smoking
or gastrites. Take Tab Pantoprazole
and stop smoking. Do regular exercises and drink plenty of fluids. If morning cough continues then try Tab Montelukast
10mg for a month. Hope this will help you.
Consult your doctor for examination and further management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
