Hello. Thank you for asking at HCM. I went through your history and would like to make you suggestions as follows: 1. When you have symptoms of allergies, I would suggest you to take montelukast and antihistamines like levocetirizine for temporary relief. 2. For treatment of the allergy, I would suggest you allergy testing which will help you to identify the substances you may be allergic to and also to know the measures to avoid them. 3. Based on allergy testing results, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune syste to improve allergy symptoms on long term basis. 4. In addition to above, I would also suggest you regular breathing exercises and healthy nutrition (adequate green leafy vegetables, fruits, sprouts, etc) which will improve your lung capacity and immunity respectively. 5. In general, please try to avoid exposure to dusts, smokes and air pollution as much as possible. Hope above suggestions will be helpful to you. In my opinion, you should consult an Allergist-Immunologist. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
