Asthma hit-and-run

Just had an asthma attack out of nowhere. I thought I was done with this...

Three years ago I had a respiratory infection that turned into a dangerous asthma attack, so they gave me medication to treat the inflammation and an inhaler for the asthma. Since about a month after the initial attack, I haven't had to use the inhaler.

Three years later, driving in my car, BAM. Coughing, wheezing, sweating.

I've got a doctor appointment later this month, so I'll add it to the list of maladies I need to ask a physician about. (I've been saving them up!)

Ugh. I really don't like the idea of severe asthma attacks separated by years.
