[|AI|]  Hello. Thank you for asking at Chat Doctor. I went through your sons' history. From his history, I would suggest him as follows:1. Were I treating him, I would prescribe daily fluticasone propionate intranasal spray in each nostril. It is important that he should use the spray with proper technique.2. At present, I would also prescribe him daily tablet montelukast and levocetirizine in the evening.3. I would suggest him to avoid exposure to dusts, smokes and air pollution as much as possible. It would be better if he does not smoke if he smokes.4. I would also prescribe him vitamin C for 2-3 months.5. A healthy diet rich in vitamins and minerals (adequate amounts of green leafy vegetables, fruits, sprouts, etc.) will help him in a longer run.6. Personally I would suggest him allergy testing, which will help him to identify substances which are causing troubles to him. Hope above suggestions will be helpful to him. Wish him the best of the health. Should you have any further query, please feel free to ask at Chat Doctor. Thank you & Regards.
