[|Human|] My doctor sad that I have asthma. He has treated me for forty years. Even though I have been on Atrovent hfa and asmanex. Last week afeter Christmas I woke up in the midle of the night with a cough that felt like knife in my chest. The doctor put me prednisone again. What causes this? I have no fever.
[|AI|]  Hellos you are taking treatment for asthma for 40 years (Atrovent and Asian) . Last weeks you had sever cough in the middle of night, doctor advise steroid (prednisolone). In my opinion such symptoms may be due to these reasons, these include:1 COPD (CONGESTIVE OBSTRUCTIVE PULMONARY DISEASE).2 Asthmatic attack due to sever allergy. Sometimes an old asthmatic patient feel such symptoms .3 Cor pulmonale. These symptoms in your case may be due to above-mentioned disease and this is common in an old asthmatic patient. So consult a pulmonologist and sort out this problem. Good luck.
