Most coughs are caused by viral infections, such as the common cold or flu, and tend to improve within 1 to 2 weeks. You can manage your symptoms at home by staying well hydrated, resting, and using over-the-counter remedies such as honey and lemon drinks or paracetamol to relieve throat discomfort or fever. Avoid exposure to irritants such as smoke and dust. Seek medical advice if the cough lasts more than 2 to 3 weeks or if you develop chest pain, high fever, or blood in your sputum.

A cough lasting 2 days is usually due to a common cold or a mild viral infection and typically resolves on its own. Since your cough comes and goes, it may also be triggered by environmental irritants such as dust or smoke or by a mild allergic reaction. You should rest, stay well hydrated, and drink warm fluids such as tea or soup. You may also try honey to soothe the throat while avoiding irritants. Consult your doctor if the cough lasts more than two weeks or if you develop chest pain or worsening symptoms.
