Just been told I have adult onset asthma after X-rays and blood work.
Everyone I've mentioned it to said it's not possible to just suddenly develop it as an adult and it's something you have from a child.
I've been referred to an asthma centre next week to test for allergies and discuss treatment. Treatment?! I'm a little in shock and don't really know a thing about asthma. Googling it briefly scared the living piss out of me!
I've got a horrible suspicion after having cats all of my life I've just become allergic to them. 
Anyone else have adult onset asthma? Or suddenly develop an allergy to their beloved pet?
Dh is being really 'oh well it's not anything serious at least' which is pissing me off a little as I feel it might be and I'm going taking steroids for a few months in the best scenario.
