Symptoms of bronchitis include coughing up yellow-grey mucus, sore throat, wheezing and having a blocked nose. Acute bronchitis may be responsible for the hacking cough and phlegm production that sometimes accompany an upper respiratory infection. In most cases, the infection is viral in origin, but sometimes it's caused by bacteria.
