<s>[INST] at night and when i go to bed i feel fine and when i wake upat night and when i go to bed i feel fine and when i wake up I feel like I cant get a good breath and I start coughing and and then at night I am okay again. What could it be? during day theis is sound in mu lungs [/INST] Thanks for your question on Chat Doctor. I can understand your concern.Nighttime coughing and breathing difficulty with day time wheezing (whistling sound from lungs) are commonly seen with asthma. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose asthma, but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Oral Combination of levocetrizine and montelukast at nighttime is also beneficial. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
