I am experiencing a strange, fluttering/bubbling sort of sensation in the left of my chest. I do have asthma, but I ve taken my rescue (blue) inhaler, but it has not eased the tightness in my chest or the fluttering/bubbly feeling. I do have a brown inhaler that I take at the beginning of the day, and I am also on 10 mg of an anti-depressant for general anxiety disorder.
