I'm sorry to hear you're experiencing a severe headache along with cold and cough symptoms. These can be quite uncomfortable.

For relief, you may consider the following measures:

• Medication: A combination tablet containing Paracetamol (for pain and fever), Phenylephrine (to reduce nasal congestion), and Chlorpheniramine (an antihistamine to relieve allergy symptoms) can help ease your headache, congestion, and cold symptoms. Such medications should be taken exactly as prescribed by a doctor to avoid side effects.

• Rest: Ensure you get plenty of rest to help your body fight the infection.

• Hydration: Drink warm fluids like herbal teas, soups, and plenty of water to stay hydrated and soothe your throat.

• Home Remedies: Inhale steam with added eucalyptus or menthol oils to relieve nasal congestion. Use a humidifier in your room to keep the air moist.

• Avoid Irritants: Stay away from smoke, strong perfumes, or other irritants that can worsen your symptoms.

If symptoms persist beyond a few days, worsen, or if you experience difficulty breathing, high fever, or severe pain, please consult a general physician or an ENT (ear, nose, and throat) specialist promptly.
