Absolutely you probably got asthma from being in this house.  I have had asthma since age 32 and I am now 48, so I have done a lot of research on asthma.  If someone is exposed to high levels of mold, mildew and bacteria for extended periods of time, the spores of mold attach themselves to the lining of your lungs and damage the lining of your lungs, thus giving you asthma.  Anytime any of these agents are breathed into your lungs for prolonged periods of time, asthma is the end result due to them damaging the lining of your lungs which is not reversible.  Make sure you see a pulmonologist and he will give you a Pulmonary Function Test which will test the amount of lung damage you have.  He will no doubt give you a fast acting inhaler (Proventil, Albuterol, etc.) and also a preventive inhaler (Advair most likely) and Singulair to take at bedtime. Make sure you take these meds diligently and you will feel much better and your asthma should be kept under good control.  Be sure to follow up ever 6 months or so with your doctor and see him immediately if there is any change in your breathing.  Good luck and God Bless
