Detailed Answer:
Thank you for asking

Usually there are 8 basic reasons of Resistant cough. Yours is likely a chronic bronchitis.

Reason 1: Irritated Airways After a Cold or Flu

Reason 2: Underlying Health Problems
Burping
Heartburn
Ongoing cough
Regurgitation
Insomnia
Loud snoring
Nighttime choking or gasping
Repeated awakenings
Sleepiness during the day

Reason 3: Stress

Reason 4: Not Drinking Enough Fluids

Reason 5: Overusing OTC Nasal Decongestant Spray

Reason 6: Air That's Too Dry or Too Moist. "Dry air -- especially common in the winter -- can irritate a cough," People should aim for humidity levels of 40% to 50% in their homes, winter and summer

Reason 7: Bacterial Infection

Reason 8: Your Blood Pressure Medicine HCTZ is notorious for worsening pulmonary congestion and edema and exacerbate pulmonary symptoms.

Nut shell, You need symptomatic management for this and meanwhile sorting out the etiology of this recurrent chronic bronchitis.

Central cough suppressants (eg, codeine and dextromethorphan) – Short-term
symptomatic relief of coughing in acute and chronic bronchitis

Short-acting beta-agonists (eg, ipratropium bromide and theophylline) – Control of bronchospasm, dyspnea, and chronic cough in stable patients with chronic
bronchitis; a long-acting beta-agonist plus an inhaled corticosteroid can also be offered to control chronic cough

Nonsteroidal anti-inflammatory drugs (NSAIDs) – Treatment of constitutional symptoms of acute bronchitis, including mild-to-moderate pain

Antitussives/expectorants (eg, guaifenesin) – Treatment of cough, dyspnea, and wheezing

Mucolytics – Management of moderate-to-severe COPD, especially in winter

I hope it helps. Take good care of yourself and dont forget to close the discussion please.

may the odds be ever in your favour.
