<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, I think I got a problem with my lungs. I ve been coughing for nearly 6 month. I start feeling a bit dizzy when I cough. I cough at random times it starts off like a spasm. If I cough I can t stop for some time, could be 5-20 min in a row. I can breathe while coughing so I don t think it s asthma or something. I think it s something chronic but I m still scared if it s something worse. I got no other symptoms or chronic deceases. Age is 20. Male. When I use cough syrups like codeine it really helps for a while but sometimes meds don t help at all. What do you think it could be?  <response>: Hello! Have you ever noticed any particular precipitating factor for your cough ? Does it happen on exposure to dust or cold ? Any increase in cough before or after meals ? Do you have any problem with digesting the food you take ? Any symptoms of upper abdominal pain or regurgitation of food? Do you have running nose, facial pain or feeling of mucus tricking down your throat ? Cough does not necessarily mean it should be a problem with your lungs. Sometimes inflammation of your nose throat and even reflux disease can cause cough. Sometimes cough can be the only presentation in asthmatics too. So kindly get yourself checked by a physician and a chest ray if needed.
