I'm sorry to hear you're experiencing throat infection with swelling and a dry cough. Here are some steps you can take to help relieve your symptoms:

• Stay Hydrated: Drink plenty of warm fluids like water, herbal teas, or warm water with honey and lemon to soothe your throat.
• Rest Your Voice: Avoid straining your voice to reduce throat irritation.
• Use a Humidifier: Moist air can ease throat dryness and coughing.
• Avoid Irritants: Stay away from smoke, strong perfumes, or pollution that can worsen your symptoms.
• Over-the-Counter Medication: A medication like Solvin Cough Tablet, which contains ingredients to relieve dry cough and allergic symptoms, may help. However, it requires a doctor's prescription and should be taken under medical supervision.

If your symptoms worsen, such as increased swelling, difficulty swallowing or breathing, high fever, or persistent cough beyond a few days, please consult an ENT (Ear, Nose, and Throat) specialist promptly.
