Hello,
Your symptoms of severe cough with green sputum and throat irritation for three days are most consistent with an acute respiratory tract infection, such as viral bronchitis.
Green sputum indicates inflammatory activity but does not necessarily mean a bacterial infection or that antibiotics are required.
Other possibilities include postnasal drip, influenza, COVID-19, or occasionally pneumonia, particularly if fever or breathlessness develops.
Most uncomplicated viral respiratory infections improve gradually within 1â2 weeks, although coughing may persist longer.
Next Steps
Consult a general physician if the cough is particularly severe, worsening, or interfering significantly with sleep. Drink adequate fluids and consider warm water with honey to soothe throat irritation. If you develop fever, breathlessness, or chest discomfort, your doctor should assess your oxygen saturation and lung examination, with a chest X-ray if pneumonia is suspected. Avoid starting antibiotics such as azithromycin or amoxicillin without medical evaluation. Green sputum alone is not an indication for antibiotics.
Health Tips
Avoid smoking, dust exposure, and cold air if these worsen your symptoms. Sleep with your head slightly elevated and consider warm saline gargles for throat irritation. Seek medical attention for difficulty breathing, chest pain, coughing up blood, confusion, or rapidly worsening symptoms. My recommendation: A viral respiratory infection is most likely based on the short duration, but the severity of the cough warrants assessment if it continues or worsens. Supportive treatment is usually sufficient unless examination suggests bacterial pneumonia or another complication. Wishing you a speedy recovery!
