[|AI|]  Hi, Welcome to Chat Doctor, Here, your coughing with sputum could be due to acute bronchitis, allergic bronchitis or upper respiratory infection etc. You may undergo routine blood investigation with sputum smear tests and X-ray chest to rule out any other pathology of lung. You will require full course of antibiotics (quinolones or cephalosporins) with anti-inflammatory and antiallergic (antihistamines or steroids) with supportive treatment. Avoid taking cold water or fruit juices which might exaggerate your coughing. Consult pulmonologist for further advise.
