I'm sorry to hear that you experience sneezing for such a long period each year. This pattern suggests you might be dealing with seasonal allergic rhinitis, commonly caused by allergens like pollen during certain months.

Here are some steps you can take to manage your symptoms:

• Avoid Allergens: Try to stay indoors on high pollen days, keep windows closed, and use air purifiers if possible.
• Medications: Antihistamines and leukotriene receptor antagonists can help reduce allergy symptoms. For example, a medication combining montelukast and bilastine is often used to relieve sneezing, runny nose, and congestion by blocking allergic reactions and inflammation.
• Consult an Allergist: A specialist can confirm the diagnosis and recommend appropriate treatment, including prescription medications or allergy testing.
• Home Care: Regular nasal saline rinses can help clear allergens from your nasal passages.

Since your symptoms persist for many months, it is important to consult an allergist or an ear, nose, and throat (ENT) specialist. They can provide a tailored treatment plan and ensure there are no other underlying issues.
