### input:
I get allergic cold everytime there is a change of climate. I also allergic to dust, kerosine, pesticides,smoke,etc.  It starts with sneezing and then broncial infection and it linger for a few day. I also tend to get throatirritation and cough. I have done all the allergic tests, etc; seen all the doctors possible the ENT, Chest specialists, etc.  For some time I am okayand then after about 4 months it reaccures. In such a case what do I do?

### output:

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 suggest you skin prick tests for common aero-allergens like house dust mites, molds, regional pollen, insect proteins, animal dander, etc. Usually qualified Allergists perform such skin prick tests.2. Based on allergy testing, an Allergist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms over a long period and reduce recurrences.3. For symptom control, I would suggest you to take combination of montelukast + levocetirizine. If you have wheezing/bronchial symptoms, I would also add albuterol to your treatment.4. Regular nasal saline washes, steam inhalation and warm saline gargles will also help you in a long run.5. In general, please avoid exposure to dusts, smokes and air pollution as much as possible.6. If stress is an important factor for you, regular relaxation and meditation will also help by reducing stress. Stress is an important trigger for allergies. 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.
