I didn't always have asthma. When I went away to college and came back home for Thanksgiving, that's when my symptoms began. I sadly developed allergies to the kitties I grew up with, and it triggered my coughing, wheezing, and chest tightness. It's pretty common to develop adult-onset allergies for a variety of reasons, and I guess I won the lottery when I developed both allergies and asthma. It's well-controlled with daily medicine, so I rarely notice symptoms, unless I have a cold or end up in a room filled with pet hair. What about you?
