I happens at work and other places and people think I am sick but I m not. what can I do? [/INST] Thanks for your question on Chat Doctor. Coughing especially in night can be seen in many causes but most commonly seen in 1. Cardiac diseases like left ventricular failure2. Asthma3. Lung infection. So I advise you to consult pulmonologist first and get done chest x-ray and PFT (Pulmonary Function Test) to rule out asthma and lung infection. Also get done ECG and 2D ECHO to rule out cardiac failure and other valvular heart diseases. Start antihistamines and get done these tests. </s>
