I have symptoms of acute bronchitis, it hurts to breathe (slightly), and I can t take deep breaths in without coughing severely. I play trumpet in marching band, and ALSO have my band lesson tomorrow, and I was wondering, because of my problem breathing, if I should continue playing. Please understand that I have an extremely important part in the band, in which I have to work up to hitting a high C (which requires a lot of deep breathing for me) so the answer to my question is urgently important to me. Thanks.
