Prolonged cough and expectoration of sputum

Sputum production and coughing can be caused by a variety of factors, the most frequent of which is an infection. Cough is a sign of many respiratory disorders, thus it is frequently missed or misdiagnosed as bronchitis, bronchiectasis, or common pharyngitis-tonsillitis. Sputum expectoration is a sign of increased secretions caused by bronchial airway irritation or injury. If a patient coughs for more than three weeks and medications do not relieve the cough, pulmonary Tuberculosis must be considered.

Coughs that don't go away bother the sufferer more and more at night. Infection is the most common cause of coughing and expectoration. If you have had a cough and green sputum for more than three weeks, you should consider pulmonary Tuberculosis. If you have any of the aforementioned symptoms, get medical treatment right immediately. Never be subjective, and accept it as a normal symptom
