I'm sorry to hear you're experiencing fever, painful swallowing, and a persistent cough. These symptoms could be due to a throat infection, which might be viral or bacterial.

Here are some general steps that may help:

• Rest and Hydration: Drink plenty of warm fluids like herbal teas, soups, and water to soothe your throat and stay hydrated.
• Pain Relief: Over-the-counter pain relievers such as paracetamol can help reduce fever and throat pain.
• Saltwater Gargle: Gargling with warm salt water several times a day can ease throat discomfort.
• Avoid Irritants: Stay away from smoke, strong odors, and cold air that can worsen your cough or throat pain.

Since your symptoms include fever and painful swallowing, it is important to see a doctor, preferably an ENT (Ear, Nose, and Throat) specialist or a general physician. They can determine if you have a bacterial infection that might require antibiotics like Azithral-500 (Azithromycin), which is used to treat bacterial respiratory infections but should only be taken under medical advice.

If you experience difficulty breathing, high fever, or worsening symptoms, seek immediate medical attention.
