I've had a virus/flu thing which has left me quite wheezy and for the first time in about 15 years have had to have a blue inhaler. My puffometer (peak flow thingy!) reading at the GP was 400 - is that OK and will it go once I'm better?
I don't like the way the blue inhaler makes me feel when I've taken it - trembly and on edge - but it does ease my breathing temporarily.
