I have just been to the doctors because I have had trouble breathing for the last few weeks and today it has been accompanied by a cough! I was thinking that maybe the mould was getting into my lungs but apparently the effect of mould isn't lasting, it's only while you are in the room with it so that's ruled out. The doctor did say that it could be related to stress so I have got a peak flow meter and have to monitor my results 3 times a day to see if it's worse at any time or if it gets worse or improves. Just more hassle but there ya go!
