This pattern sounds like airway hyperreactivity. Thank you for the detailed history - it is very helpful. The pattern you describe (throat irritation then a choking cough, worse in the mornings, triggered by outdoor air, dust, trees, pollution and humid weather, no wheeze) most often comes from upper airway causes: allergic rhinitis with post-nasal drip, laryngeal hypersensitivity, or silent acid reflux, and cough-variant asthma or airway hyperreactivity is also possible. The tests that actually answer this are spirometry with a bronchodilator reversibility test, an ENT laryngoscopy, and allergy testing (skin prick or specific IgE); a repeat HRCT is usually not needed since 2020 was similar and normal. Meanwhile, saline nasal douching twice daily, an antihistamine or a steroid nasal spray as advised by your doctor, avoiding known triggers with a mask outdoors, and reflux measures (no late dinners, head end of bed raised, avoid smoking and alcohol) help most patients considerably. Please treat it as an emergency if you ever have true difficulty breathing at rest, noisy breathing (stridor), lips turning blue, or you nearly faint during an episode - go to the nearest emergency in that case. You can book a consult with me on Practo and I will help you plan these tests in the right order.

HRCT scan doesn’t show any obstructive or restrictive airway disease.so see a pulmonologist or allergy specialist and go ahead with other investigations for allergy or airway hypersensitivity etc

It could be angioedema. Ever time you are getting exposed to allergen, you are having recurrence of these symptoms. Check your histamine levels and IgE levels. And review with reports

Allergic condition most probably

Allergic

Please consult a physician physically for clinical evaluation.

Kindly consult for detailed evaluation

No covid Steam inhalation with Vicks or eucalyptus oil two times before meals. Ab phyllinsr200 two times after food for five days.  Taxim o200 two times after food for five days. Zerodol sp three times after food for five days. Montek lc one at night for five days.

It could be due to upper airway cough syndrome, reactive airway disorder, asthma, gerd etc.Ideally you should consult a pulmonologist for a clinical examination and lung function tests and provocative tests, allergy tests

The HRCT is normal, but the choking and coughing episodes need evaluation for asthma or other related causes. Please consult me for a proper assessment and appropriate tests and an individualized treatment plan.
