I'm sorry to hear you're experiencing a runny nose, itchy eyes, and sneezing. These symptoms often suggest an allergic reaction or seasonal allergies.

Here are some steps you can take to find relief:

• Avoid Allergens: Try to stay away from known triggers like dust, pollen, pet dander, or strong odors.
• Keep Indoor Air Clean: Use an air purifier or keep windows closed during high pollen times.
• Use Saline Nasal Spray: This can help clear nasal passages and reduce irritation.
• Over-the-Counter Antihistamines: Medicines containing levocetirizine or montelukast can help reduce allergy symptoms. For example, a combination tablet like Montemac L (which contains montelukast and levocetirizine) is used to relieve symptoms such as runny nose, sneezing, and itchy eyes. However, this should only be taken if prescribed by a doctor.
• Avoid Self-Medication: Do not start any new medication without consulting a doctor, especially if you have other health conditions or are taking other medicines.

If your symptoms persist beyond a few days, worsen, or you experience difficulty breathing, high fever, or severe discomfort, please consult an allergist or an ENT (ear, nose, and throat) specialist promptly.

Taking care of your symptoms early can help you feel better and prevent complications. Please see a specialist doctor for a proper evaluation and personalized treatment.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
