Hi,
Your symptoms are suggestive are suggestive of the following:
- Nasal discharge but unproductive cough indicate the cause to be allergic. The same allergy is causing continuous coughing without any mucus as irritation is the cause.
- Feeling of nasal discharge and postnasal discharge can be due to irritation and oedema at the back of nose.
Hence I would advise you the following in addition to the things already done:
- First of all try to identify the foods, beverages, factors, atmospheric changes, mould, mildews, pollen, hair of pets and a keen observation only can. Avoid all these.
- CT scan of sinuses and nose and
second opinion of an ENT Surgeon, further evaluation, examination and surgical and medical treatment as would be needed.
- ENT
Endoscopy,
bronchoscopy to know whether there is any cause in the lower
respiratory tract and to get it treated as you have hacking cough.
- Pulmonary function tests can help further.
- Lastly a psychological factor has to be considered and get treated if stress or
anxiety is present.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
