To cut a long story short I have moved home and cannot work out why m asthma is playing up. On the second day I descovered a gass leak in the property, I ended up in A&E and now have the all clear. The property is also brand new so there has been a lot of wood, tile etc dust about. The weather has also change quite quickly and I was wondering if this was the trigger. Could it be a mixture of all three? It seems to be worse at night too. Can anybody recommend any releif. I have an inhalier which I am using but it makes my heart beat fast and I really don't like that feeling.
