I had an acute asthma attack Wednesday which nearly landed me in ICU. When I finally recovered I got sent home with a 5 day course of prednisone and got told to go back to my local GP even though I'm under a consultant. So I did what they said anyway and went to my GP today and they gave me more pred. My peak flow on a very good day is 460 but normally about 350 but for the past couple of weeks it has been 160-210. Why does nothing seem to help anymore? I have my reliever quite a lot throughout the day and seems to help for about 5-10 minutes or so but then after that it doesn't seem like I have had it at all... Anyone else in the same boat as me? Many thanks.
