HI, thanks for using healthcare magic Asthma symptoms occur when the airways close down making it difficulty to breath. The symptoms of an asthmatic attack are cough , shortness of breath, chest pain and wheezing. Night time coughing indicate the asthma is not in control. There are different triggers for asthma such as infections, dust and other allergies, post nasal drip, emotion, exercise You need to use a preventer and a reliever inhalor. The preventer would reduce the inflammation in your chest and reduce the chance of an attack occurring. The reliever would help you when an attack occurs. The preventer should be continued, though the dose may vary sometimes depending on how well you are. Since you have seen many doctors, you may want to consider a pulmonologist (lung specialist) that would help you get in control. I hope this helps
