Hello. Thank you for asking at HCM. I went through your history and would like to make following suggestions to you: 1. Were I treating you, first of all I would like to review your technique of using inhaler. If it is not perfect, there is possibility that enough drug is not entering your lungs and hence may be ineffective. 2. I would suggest you tests like chest X-ray, spirometry with post-bronchodilator reversibility and allergy testing. These tests will help confirm the diagnosis. As you are already taking right medications for asthma and still not better, I would like to confirm the cause of cough. Depending upon reports of allergy testing, an allergist-immunologist may prescribe you allergen specific immunotherapy which works on your immune system and will help allergy symptoms gradually. 3. I would like to know whether you smoke, if yes, please stop smoking. Please make sure that you are not exposed to second-hand smoke at home/office also. 4. I would like to know whether you have any symptoms of sinusitis - nasal congestion, headache, facial heaviness, etc. In that case, cough can be due to sinusistis and an otorhinolaryngologist consultation will be helpful to you. He will examine your nasal cavity from inside and may identify the cause. 5. In general, please avoid exposure to dusts, smokes and air pollution. 6. Regular breathing exercises (like Pranayama & Yoga) and a healthy diet rich in vitamins & minerals (adequate amounts of green leafy vegetables, fruits, sprouts, etc) will also improve your lung capacity and immunity respectively and will help you in a long run. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
