[|AI|]  Hello. Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions to you as follows:1. First, yes, cough can definitely be the only symptom of asthma, but not very commonly. Especially if your cough is improved with corticosteroid inhalers and worsened by stopping them, there is high chance that the cough be asthmatic.2. Also, allergic rhinitis and sinusitis due to allergies can also cause cough. So it is important to identify the cause of the cough.3. Asthma cannot be definitely diagnosed with x-ray or blood tests. I would suggest you spirometry with reversibility with bronchodilator testing, which can diagnose or rule out asthma.4. For allergic cough, I usually prescribe my patients a combination of montelukast and levocetirizine which improves allergic rhinitis, sinusitis as well as asthma.5. I would also suggest you regular breathing exercises and avoidance of dusts/smokes/air pollution.6. I would also suggest you allergy testing which will help you to identify the substances causing troubles to you and also how to avoid them. Hope above measures will be helpful to you. Should you have any other concern, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards.
