question: I have a mold and mildew allergy. About 10 days ago, my husband replaced an upstairs toilet. It took about two days but in that time, the large pipe was exposed. He put paper towels in the hole but I don t think it helped. I have COPD and asthma and since then I ve been feeling awful. Congested, coughing and my legs , especially, have been very weak. I was getting off the treadmill a couple s of days ago and my legs almost gave out. Can you help please?
