I'm sorry to hear you're experiencing severe cold and nose pain from frequent sneezing. Here are some steps you can take to help relieve your symptoms:

• Rest and Hydration: Ensure you get plenty of rest and drink warm fluids like herbal teas or warm water with honey to soothe your throat and keep hydrated.
• Nasal Care: Use a saline nasal spray or rinse to help clear nasal passages and reduce irritation.
• Avoid Irritants: Stay away from smoke, strong perfumes, or allergens that might worsen sneezing.
• Over-the-Counter Antihistamines: Medications like levocetirizine (an antihistamine) can help reduce sneezing and nasal allergy symptoms. However, these should be taken under a doctor's guidance.
• Pain Relief: For nose pain, applying a warm compress gently over the nose can provide comfort.

If symptoms persist beyond a week, worsen, or are accompanied by high fever, facial swelling, or severe headache, it is important to consult an ear, nose, and throat (ENT) specialist for a thorough evaluation and appropriate treatment.
