Hello.
Thank you for asking at HCM.
I went through your history and would like to make following suggestions:
1. Yes, sneezing and blocked nose can be due to pollen allergies.
2. However, there are other causes also like house dust
mite allergy,
fungal allergy, pet dander allergy, etc.
3. So I would suggest you allergy testing which will help you identify the
substance causing allergy to you. This will also help you to know avoidance measures.
4. I usually prescribe my such patients regular
montelukast and
levocetirizine which controls the symptoms of allergies.
Hope above suggestions 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.
