Today I Had An Asthma Attack At The End Of

Today I had an asthma attack at the end of a water aerobics class today. Unable to breathe, used 2 puffs of rescue inhaler. Today, I was dizzy, nauseous, my hands were cold, face blood red, and my legs went into a quiver. I did not go with EMS; my chest was tight and heavy. I did see my doctor who ordered chest exray and Levaquin as I was still wheezing and tight. I typically do not have issues with breathing unless I have a respiratory vius like a cold which immediately turns into bronchitis and months of coughing. Yes, my co-workers leave tea and cough drops on my desk because after a month they hard tired of hearing me.
I had my inhaler because I had be short of breath for couple weeks, complaining of tiredness, and an occasional dry cough. We recently had water damage at work. The carpet was cleaned, sprayed by a professional, and a dehumidifier added about a month ago. Could this be why I am lung issues even though the damage was treated?
