<s>[INST] Hi doctor. I have this persistent cough that will come with certain timing in the day, particularly early morning before sunrise and in the evening before sunset. When I cough too hard, I will have this pins and needles sensation in my hands and feet. At the same time my asthma will come either before or after the episode. I will usually resort to my inhaler and herbal cough syrup at home. After awhile it will go away. Please explain. [/INST] Hello, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. I would like to know more about you like your age, since when you have asthma, any nose/sinus symptoms, any allergies, previous investigations, which inhalers are you using, your habits, environment, etc. Above details would help me to know more about you and hence to make more specific suggestions.2. At present, from your provided history, I would suggest you that your cough bouts may be a sign of insufficient control of asthma. I usually suggest my such patients to increase their controlled medications like inhaled corticosteroids or addition of montelukast.3. I would suggest you spirometry with post-bronchodilator reversibility testing which measures lung capacity as well as helps your doctor to choose appropriate medications.4. Furthermore, I would also suggest you allergy testing for common air-borne allergens such as house dust mites, molds, pollen, insect proteins, animal dander, etc. This will help you to know the substances causing allergies to you as well as to know the measures to avoid them.5. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms.6. In general, please avoid exposure to dusts, smokes and air pollution as much as possible.7. Regular physical exercises including breathing exercises as well as a healthy diet rich in vitamins & minerals will also help you by improving your lung capacity as well as immunity respectively on a long run. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health ahead. Thank you & Regards. </s>
