Asthma

I am suffering from Asthma for the last 13 years. Nowadays I am facing much more problems due to it like breathing and cough problem. Even though I am taking medicines L Montus AB, Doxofly 400 and in the night along with Nemolize but my health is not getting better. Pls suggest me what should I do

Well, really, you should go back to your GP and tell her/him this, shouldn't you? Has your GP ever referred you to a specialist?
