Asthma...

Recently, I can't get to sleep well because I can't help coughing during nighttime. I am afraid that it is asthma. When I was a pupil, I was suffering from asthma. Because of it, I went to the hospital twice. However I haven't suffered from it since. Now I keep coughing since I got cold on the first April. I don't think it is just cold. Maybe I will go to the hospital later. I hope I don't have to worry about it and get to sleep well. (> <)
