I was born with eczema and I started to have bronchospasm few years ago. The doc said it might be asthma and prescribed me with salbutamol. However, i found that I don't have the common syptoms as asthmatic people .e.g wheezing or coughing, and it doesn't disturb my sleeping as well. I just feel the bronchi contract and chest tightness which go away after few minutes later without taking the inhaler. I've taken the inhaler before but i found it no use, so i didn't use it anymore.
