While this article is written for the general public, not for those with CLL, I found the description of how our mucal secretions vary through the normal inflammatory sequence with respiratory infections from the common cold, sinusitis and acute bronchitis respectively quite enlightening. John Turnidge, Affiliate Professor of Molecular and Biomedical Science, University of Adelaide has summarised this in an an easily readable article: theconversation.com/health-...
Be aware that with CLL, infections we previously used to brush off easily can take longer to clear and become more serious due to our compromised immune systems. Developing pneumonia can have serious repercussions, so you should definitely go to your doctor if you feel your respiratory infection is worsening. In our case, a script or several for antibiotics - even if there isn't a bacterial infection, is a worthwhile compromise. Finally remember that prevention is better than cure - particularly in our case, so do ensure you are up to date with flu and pneumonia vaccinations.
