I'm sorry to hear that you're experiencing recurring cold symptoms with sneezing and a runny nose. These symptoms often suggest allergic rhinitis or recurrent viral infections. Since you have tried cetirizine and other antihistamines without lasting relief, here are some steps you might consider:

• Consult an Allergist or ENT (Ear, Nose, and Throat) Specialist: They can help identify if allergies or other causes are behind your symptoms through detailed history, examination, and possibly allergy testing.

• Avoid Known Triggers: If you suspect allergens like dust, pollen, or pet dander, minimizing exposure can help reduce symptoms.

• Consider Nasal Irrigation: Using saline nasal sprays or rinses can help clear nasal passages and reduce irritation.

• Review Medication Use: Sometimes, antihistamines alone may not be sufficient. A specialist might recommend additional treatments such as nasal corticosteroids or combination therapy.

• Monitor Symptom Patterns: Note if symptoms correlate with specific environments, seasons, or activities to aid diagnosis.

Since your symptoms improve after about a day, it might also be helpful to rule out other causes like viral infections or non-allergic rhinitis.

Please consult an allergist or ENT specialist for a thorough evaluation and personalized treatment plan.
