Hi there I understand your concern... Avoid irritating stimuli (eg, cold, dry air; indoor or outdoor air pollutants) that may provoke coughing. An upright or semiupright posture, such as sleeping with the head and shoulders raised, may decrease cough related to pharyngeal secretions...over the counter antihistaminics will be beneficial to you...consult nearest pulmonologist for clinical examination they will do the needful.
