My 7 yr old son has asthma. He has had it since he was 1-2 yrs old. He seemed to be growing out of his asthma when lots of mould started appearing in my bathroom and the bedrooms. I have the vents open all the time and the windows open when he is at school. Now his asthma has started getting bad again. He has just got over a chest infection and was on anti biotics for 5 days. I went to the drs to get a medical letter to give to the council and the dr said he would do it but said that mould really doesnt affect asthma. What is true and what to do????
