Hi,
Noted your short history of chronic and
severe coughing for 3 weeks, no comment on treatment taken, investigations or so.
I would advise you the following:
First of all, consult your Doctor for clinical evaluation, examination and investigations like that of blood, of sputum and X-ray of chest as the coughing is present for 3 weeks.
All these things will give a proper diagnosis of the cause of cough so that a specific treatment can be started under the care of a Doctor and you get a relief and cure.
Do not treat yourself as there can be a cause that needs to be seen for such a long duration of coughing.
You can take steam inhalation and take an
anti-tussive.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
