Hello. Thank you for asking at HCM. I went through your history and would like to make suggestions to you as follows: 1. High absolute eosinophil counts indicate long-standing allergy. 2. DEC helps another cause of high eosinophils such as tropical pulmonary eosinophilia but not allergy. 3. Were I treating you, I would suggest you regular montelukast. I would also suggest salbutamol inhaler to be used on as-and-when-needed basis for wheezing. 4. If your chest pain is not relieved by above treatment, I would prescribe you an antacid like omeprazole or pentoprazole. 5. For long term treatment of allergy, I would suggest you to consult an Allergist-Immunologist who may perform allergy skin test and suggest you allergen specific immunotherapy which works on immune system to improve allergy symptoms gradually. 6. In general, I would suggest you to void exposure to dusts, smokes & air pollution. 7. Regular breathing exercises and a healthy nutrition will help you to improve your lung capacity and immunity respectively in a long run. Hope above suggestion 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.
