I'm sorry to hear that you've been experiencing a dry cough for five days. A dry cough without a runny nose can be caused by various factors such as viral infections, allergies, irritants, or even early signs of respiratory conditions.

Here are a few points to consider:

• Duration and symptoms: Since the cough has lasted for several days, it’s important to monitor for any new symptoms like fever, shortness of breath, chest pain, or worsening cough.
• Possible causes: Dry coughs can be due to viral infections like bronchitis, post-viral cough, or environmental irritants such as smoke or dust.
• When to seek care: If the cough persists beyond two weeks, worsens, or is accompanied by other symptoms, it is advisable to consult a pulmonologist (lung specialist) for a thorough evaluation.

In the meantime, staying hydrated, avoiding irritants, and resting can help. Avoid self-medicating with prescription drugs without a doctor’s guidance.

Please consult a pulmonologist to get an accurate diagnosis and appropriate treatment tailored to your condition.
