Iam having a fairly severe cough, which keeps me awake at night, but the last two nights when I breathe out, I hear a
whistling, static sound coming from my chest. I have no fever and I feel okay when I am not coughing.
I usually get Bronchitis when I get a cold, but I am not coughing up much and it's not green, just light yellow. I have
never had this sound coming from my chest when I breathe before. I also have a St. Judes aortic valve.
Should the whistling sound be a concern for me? Thank you
