I had a breathing treatment this morning using albuterol. It feels like a something is going on in my chest like a butterfly feeling or feeling like I have to cough when I walk. I haven't felt this before the treatment. I had a pulmonary test done to determine why I am having this flutter in my chest (It was happening once or twice a week and only for about 60 secs then the feeling was gone). Just wondering if this is a side effect of the treatment where I feel this fluttering in my chest when I walk. I am 60 year old female.
