I'm sorry to hear you're experiencing a dry cough, body pain, and throat pain from coughing. These symptoms can be uncomfortable and may indicate a viral infection or irritation in your respiratory tract.

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: Give your body adequate rest to help your immune system fight the infection.
• Use a Humidifier: Moist air can ease throat irritation and reduce coughing.
• Avoid Irritants: Stay away from smoke, dust, and strong odors that can worsen your cough.
• Over-the-Counter Medication: Medicines like expectorants can help loosen mucus and ease coughing. For example, a combination expectorant containing guaiphenesin, terbutaline sulfate, and bromhexine hydrochloride may be prescribed by a doctor to relieve cough and associated symptoms.

Since your throat pain is due to coughing and you have body pain as well, it is important to consult a general physician or a pulmonologist. They can evaluate your condition properly, rule out infections like bronchitis or other causes, and prescribe appropriate treatment.

If you experience worsening symptoms such as difficulty breathing, high fever, or persistent chest pain, seek emergency medical care immediately.
