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.
