I've picked up a chest cold. I'm not bringing up any mucous, but can feel there is some there when I get into one of my "coughing fits". My coughing is worse at night when I am lying down. Other than the cough, I feel fine. Anybody trained while having a URI? What did you do? and how intense? I am wanting to know if doing indoor spinerval tapes at moderate intensity might help shorten the length of this, or if I should just lay off for a few days? (9" snow on ground makes it impossible to bike outside right now). Thanks for any advice you can give me!
