I'm sorry to hear you're feeling unwell with a cold, headache, and fever. Here are some steps you can take to feel better:

• Rest: Give your body plenty of rest to help your immune system fight the infection.
• Hydration: Drink plenty of fluids like water, herbal teas, and fresh fruit juices to stay hydrated.
• Medication: Over-the-counter medicines like Dolo-500 (paracetamol) can help reduce fever and relieve headache. However, use it as per the instructions on the package or your doctor's advice.
• Nutrition: Eat light, nutritious meals including traditional Indian foods such as khichdi, dal, and seasonal vegetables to support recovery.
• Avoid irritants: Stay away from smoke, strong odors, and alcohol, which can worsen symptoms.
• Monitor symptoms: If your fever persists beyond 3 days, headache worsens, or you develop difficulty breathing or other concerning symptoms, please consult a doctor promptly.

Since these symptoms can be caused by various infections, it is important to see a general physician if symptoms do not improve or worsen. They can provide a proper evaluation and treatment plan.
